SSL error when accessing APS featured applications: SSL: no alternative certificate subject name matches target host name

Applicable to:

  • Plesk 12.5 for Linux

Symptoms

On attempt to access any APS applications in APS catalog the following error is thrown:

APS Catalog error: SSL: no alternative certificate subject name matches target host name 'server.tld'

Cause

The error message occurs when some kind of load balancing or intrusion detection/prevention systems are used, which acts as a proxy by terminating an SSL connection (unwraps the SSL) and forward the request via unencrypted HTTP to the web server, with a header that tells the Web server that the original request was encrypted.

Resolution

Contact network/system administrator or your networking provider.
