SharePoint – event 8311 – SSL policy errors have been encountered. Error code 0x2


SharePoint is generous in error messages, and they nearly get a reason evertytime…Just need to figure out

This time, the following error message appeared both on 2010 and 2013 farm:
sharepoint event 8311

Which give in text:

Log Name: Application
Source: Microsoft-SharePoint Products-SharePoint Foundation
Event ID: 8311
Task Category: Topology
Level: Error
An operation failed because the following certificate has validation errors:nnSubject Name: CN=Server.mydomain.netnIssuer Name: CN=my-CA, DC=mydomain, DC=net

Errors:nn SSL policy errors have been encountered. Error code '0x2'..



A certificate has been binded to IIS for SharePoint Web Services site ((binding SSL port 32844).


The server is registered in SharePoint with its short name and this certificate subject contains the FQDN name.

2 solutions:

  • Get another certificate with a matching subject name,
  • Rename server in SharePoint farm to its FQDN

That last solution was chosen, done in PowerShell.

Get servers with their registered name in farm:


Rename one server (must be done locally on the server):

Rename-SPServer -Identity MyServer -Name

Follow by a iisreset, and wait 10mn to get topology updated 🙂
