Plesk 12.x / Linux :: Error When Accessing Backup Via Reverse Proxy
Jun 3, 2015
When accessing a backup in backup-manager in a user subscription via a reverse proxy (eg. plesk panel is called as localhost:8443) I get following error:
Internal error: Failed to exec pmm-ras: (array ( 'code' => 127, 'stdout' => 'Transport error: File 'clients' not found ', 'stderr' => '', )).
Message Failed to exec pmm-ras: (array ( 'code' => 127, 'stdout' => 'Transport error: File 'clients' not found ', 'stderr' => '', )).
File Connector.php
Line 227
Type PleskPMMResponseException
This happens when I try to download the backup and also when clicking on the backup name. These are the apache settings for the reverseproxy domain:
SSLProxyEngine On
AllowEncodedSlashes On
<Location />
ProxyPass https://localhost:8443/
ProxyPassReverse https://localhost:8443/
</Location>
Being relatively new to the Linux world, I don't exactly know why my reverse proxy settings are not working. Nothing i have tried has worked.
The code below is from my old windows server what does not seem to be working in my new 1&1 vps server. I have the below code at the moment at the bottom of my httpd_ip_defult.conf file under /var/www/vhosts/system/mydomain.com/conf/
The following errors also show up in my vhosts error log:
Code:
[Sun Oct 12 23:30:56 2014] [error] (70007)The timeout specified has expired: proxy: HTTP: attempt to connect to xxx.xxx.xxx.xxx:8008 (xxx.xxx.xxx.xxx) failed [Sun Oct 12 23:30:56 2014] [error] ap_proxy_connect_backend disabling worker for (xxx.xxx.xxx.xxx) I also have mod_proxy.so , mod_proxy_http.so and mod_proxy_html.so all enabled in my main httpd.conf file at /etc/httpd/conf/
Basically, I need to fix this urgently as a core feature of my site relies on this setup.
With enabled nginx I'm unable to contact web pages via TLSv1.1 and TLSv1.2. When nginx is disabled and the pages are handled by Apache everything is fine. But only when nginx is completely deactivated. It's not enough to disable "Smart static files processing" at the "Web Server Settings for sub.domain.tld".
I tried to add "ssl_protocols TLSv1.1 TLSv1.2;" at "Additional nginx directives" at the Web Server Settings, without effect.
I think i have to modify /etc/nginx/plesk.conf.d/server.conf but this file is generated by Plesk.
We are getting the error from the SAP portal where we have installed Apache as a reverse Proxy on Windows server.
The Apache Server received an invalid response from an upstream server.
The Proxy server could not handle the request POST/irj/portal
Reason: Error reading from remote server -------------------------------------------------- Apache/2.4.9 (Win32)OpenSSL/1.0.1h Server at www.xyz.com port 80
I have received notices from several customers with this error and I checked myself. When trying to connect to a ftp hosted on my server with Plesk gives an error expired certificate, a certificate of Parallels. The solution I've found is to configure access without TLS but says it is unsafe and customers are not satisfied.
I'm not sure if it's a technical or a license issue. When I try to retrieve external services, such as purchase an ssl certificate or buy an application; I see the the following error: "Error: Error validating license."
For example: If I click on 'Tools and Settings' > 'External Services' > 'View Services' , the browser redirects to [URL] .... (as it should) and then gives me the license error. I have re-retrieved my license key, and even downloaded and reinstalled it from the Parallels Partner Channel and the problem persists. When I check the license key status from the Panel it says, "Key Update Status: License key PLSK.02557481.0016 is up-to-date." Everything else is working fine.
I am running Plesk version 12.0.18 Update #37 on Centos 6.6
I'm not sure if this is the right forum, or if anyone can suggest a message board where I might get support on this.
This is what I have. I have Apache and IIS both running on Windows 2k3.
Apache is running in reverse Proxy mode sending multiple domains/virtual hosts to IIS.
Code:
ProxyRequests Off <VirtualHost *:80> ProxyPreserveHost On ProxyPass / http://localhost:8080 ProxyPassReverse / [url] ServerName mydomain.com
</VirtualHost> Now, if I type in [url]everything works great and IIS (listening on 127.0.0.1:8080) serves the page. However, I am doing custom error trapping, so when I type in [url](and /mydirectory doesn't exist on IIS) I need to fire ASP code (via custom error messages/handling) on the IIS server and then present a data driven page.
However, Apache is returning A 502 error:
Code: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /mydirectory.
Reason: DNS lookup failure for: localhost:8080mydirectory Is there a way for me to setup Apache to pass all error checking to IIS while using it as a reverse proxy?
We have been using Apache 2.2.x with reverse proxy modules for our clients to access their OWA servers for over a year. I want to get us to Apache 2.4.x so I setup a test box with latest 2.4 on it. I fixed the config file issues since 2.4 has changes in it. OWA proxy is working on my test server with Apache 2.4. But with 2.4 I do have an issue I cannot figure out. Note that this does NOT occur with Apache 2.2. I get the following errors when using ActiveSync through reverse proxy:
[Thu Oct 17 12:19:11.670665 2013] [proxy_http:error] [pid 748:tid 8440] (OS 10060)A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. : [client x.x.x.x:20311] AH01102: error reading status line from remote server mail.nameredacted.net:443 [Thu Oct 17 12:19:11.670665 2013] [proxy:error] [pid 748:tid 8440] [client x.x.x.x:20311] AH00898: Error reading from remote server returned by /Microsoft-Server-ActiveSync
So somehow with Apache 2.4 there is some sort of timeout that was not there with 2.2.
I upgraded Plesk 11.5 to the latest version 12.0.08 # 5 and now I can not configure the external FTP backup I get the error:Transport error: unable to list directory: Curl error: Timeout was reached. Also failing the backup shows this error: Unable to rotate dump: The dump rotation is failed with code '126 'at / opt / psa / admin / bin / plesk_agent_manager line 1041.
And this one:Can not upload file 'domains/domain.tld/backup_domain.tld_info_1406210716.xml' to ftp. Error code: 1..my SO Debian 6.0.8
i have make a full Plesk Backup on my Old Server with Plesk 12.0(Ubuntu) and will restore the Backup on my new Server with Plesk 12.0(CentOS).When i will restore the backup i get this error: "Error: The source file is not a valid XML file. If you supplied an archive file containing a backup from Plesk version 9 or later, then extract the contents of this archive, and process the extracted XML file with the converter. If you want to convert a backup file from a Plesk version earlier than 9, then you first need to process it with the pre9-backup-convert utility, and then process the resulting file with the pre10-backup-convert utility."
I recently started getting errors when attempting to backup our web server.
Code:
Warning: mysql "db_xxx_0" Failed to pack files webxx-fullbackup_db_xxx_0_1_1406050308 in /mnt/backup/location [ 412107659264 bytes free of 541129271296 bytes total on mount point 0] Warning: mysql "db_xxx_0" Use of chdir('') or chdir(undef) as chdir() is deprecated at /opt/psa/PMM/agents/shared/Storage/Bundle.pm line 38. mysqldump: Error 2013: Lost connection to MySQL server during query when dumping table `wp_postmeta` at row: 1357
"Transport error: unable to list directory: Curl error: Couldn't connect to server".
This happens when I enter ftp settings for the Personal FTP Repository. I'm sure the ftp server is fine. I have it already set on other domains. It connects backs-up just fine.
I've noticed two things when connecting to the FTP server it automatically issues PASV and does nothing else. It also connects using the secondary ip which I guessing it should. Micro Update 5 is installed.
I cant restore my back up. Get following warnings:

I am having trouble with backing up a wordpress multisite.. When backup is on i am getting this error:
Not all the data was backed up into /var/lib/psa/dumps/domains/<domain>/databases/<db_name> successfully. mysqldump: Got error: 1016: Can't open file: './<db_name>/<some_table>.frm' (errno: 24) when using LOCK TABLES
Whenever I am trying to take backup through Parallels Plesk (Plesk version:12.0.18 Update #53) getting an error "Error: Insufficient disk space for backup. "
Default backup location is '/var/lib/psa/dumps' with enough space (Near 1TB). Then why showing above error message?
Version Details: Version Parallels Plesk v12.0.18_build1200140811.16 os_CentOS 7 OS CentOS Linux 7.1.1503 (Core)
why but autoupdate fails. It doesn't give a reason why it cant backup.

Some related problems have already been discussed here in the forum (e.g.: [URL] .... or this one: [URL] ...., but it all did not quite match with my problem.
if my main site hosted in usa and reverse proxy server located in UK or Canada. will my site load still quickly or be slow dramtically? both use linux and apache. or canada user will quickly load my site or still slow? how about usa customers?
I researched a few options and have come to this conclusion use Ultramonkey (LVS + HA Proxy) -> apache2 mod_php/ mod_python (serve php / python) -> lighttpd (serve static files) -> mongrel (ruby server)
I am not able to take backups of the content of the server. This is the error I get:
Error: Runtime error: The check dump failed with code '1'. The dump can contain invalid data! at /usr/local/psa/admin/bin/plesk_agent_manager line 1022.
Error: The dump have been invalidated by check-dump operation
I experienced an issue using an external backup repository on Plesk 12.0.18 machines using ftps. The ftp server uses ftps (explicit) connections.Plesk 11.5 works fine (and ordinary ftp client like Filezilla as well), Plesk 12 throws the following error when trying to add the server via the web interface:
Code: Curl error: Login denied Unencrypted connections will work. Plesk 11.5 machines (with the same settings) will work.
I've analyzed the problem and got so far: The backup manager tries to connect using "regular" transfer method + ssl, not ftp-ssl explicit.Is there a chance to force Plesk using explicit ftpes connections? Or is there another work around?Some additional infos about the (ftp) server: The ftp server is running ProFTP 1.3.4d, uses port 2000 for the control port and has a port range (2001 - 2100) for the passive connections.I tried to add the server using the address field of the gui IP:2000 and checkboxed "passive mode" and "ftps".
