Plesk API Error Messages

Post by magicspam » Thu Apr 12, 2012 12:42 pm

If you are getting messages similar to:
Error retrieving version from Plesk API: Error communicating with Plesk API: are the packages psa-api and psa-api-rpc installed?
This is being caused by the Plesk upgrade script removing some files from the psa-api-rpc package. Please remove the psa-api-rpc package and reinstall using the Plesk installation script in order to replace the missing files.


Other things to check for include:
  • Were there any recent changes or upgrades to your Plesk server made?
  • Do you have Firewall rules enabled on the server?
  • [list]
  • If so - is there a rule blocking access to port 8443?
  • If so - are there rules ahead of that permitting access to port 8443 for source IP 127.0.0.1?
[*]Does the file /usr/local/psa/admin/htdocs/enterprise/control/agent.php exist on your server? If not, reinstall the psa-api-rpc package[/*]

[*]In the Plesk Panel - Under 'Security' / 'Control Panel Access' - is the default preference set to 'Allowed' or 'Denied'[/*]
  • Is there a network entry for 127.0.0.1
[*]Has your configuration of Plesk Panel been modified to not use secure HTTPS OR modified to listen on a port different than the default[/*][/list]

In addition to the above trouble shooting steps:

We have heard reports of hosting companies overriding and disabling the API access on their customers' Plesk Panel servers. Please double check and ensure that your hosting company has not done this.
