mid server Issue: MID Server encryption keys do not match and are no longer valid.

[san1989]

Hi,

We are getting the mid server error : "MID Server encryption keys do not match and are no longer valid. To restore proper functionality, invalidate and re-validate the MID Server."

Found KB Article: https://noderegister.service-now.com/kb?id=kb_article_view&sysparm_article=KB0855813

But, after invalidating and validating again, mid server issue is getting resolved, but immediately creating the same issue in new record.

I have tried with Rekey and restarting to but nothing helps.

Please provide insight on this, Thanks in advance!

Sometimes if certificates been used, they get corrupted. You might need to load them again. I would say to check the agent logs. You will the root cause.

Hi @san1989 

I'm answering if anyone came wondering for the same issue to this thread.

Solution: "Rekey" the mid server.

Thanks and regards

Yeah, same issue for me, If I did Rekey also same error showing

If revalidation fixes the MID Server only temporarily, I’d check whether multiple MID Server records are pointing to the same installation or sharing stale encryption/key material. Reviewing the MID Server logs around the key mismatch should help identify what is triggering the repeated invalidation.
