Internal server error 500 on system/licensing- How to resolve?

[kamihi]

hi everyone! My Splunk is working correctly, but when I go to System -> Licensing the error 500 appears. On web_service.log

Do you have any ideas to troubleshoot this problem?

Do you maybe have a lot of license messages? I've seen that triggering this issue.

Did you manage to solve this, seeing the same error on 9.1.1 while trying to investigate a license violation using a Developer License.

The same issue here with 9.0.5 as well.  (after upgrade)

I'm having the same error in version 9.0.4. Did you find a fix for this?

@kamihi - Have you made any changes from the backend that could probably have broken this?

If no, you can probably contact Splunk Support to get help!!!

I hope this helps!!! Upvote is appreciated!!!

[kamihi]

no, nothing. My Splunk version is 9.0 . I really want to find the problem. Do you have any other ideas?

@kamihi - Splunk support is the best bet in this situation then.

I hope this helps!!! Upvote is appreciated!!!
