Event 15021 – An error occurred while using SSL configuration for endpoint

Lately I had the issue that SolarWinds Orion was detecting an expiring certificate on one of our servers. I have replaced every certificate on the server and double checked (of thought!) that the old certificate was deleted. But it was still complaining about an expiring date on a certificate I couldn’t find. I checked the event logs and found the event 15021, which told me something was still wrong.

I found out that a certificate was on a binding with “netsh show http certssl” in a command prompt.

It was resolved by doing the following.

  1. Open a CMD.exe.
  2. Execute “netsh http show sslcert“, and got the following back.

  3. Note down the old configuraiton and delete the binding with “netsh http delete sslcert ipport=“.
  4. Add it again with “netsh http add sslcert ipport= certhash=<new hash> appid=”{f955c070-e044-456c-ac00-e9e4275b3f04}”“.

Now the error is gone from the event log and Orion!

That’s all from now.
