Webhooks not posting to Slack

Question

We have mulitple webhooks we are using to post to various slack channels.  They were all working fine, then suddenly they all stopped working.  No admin change that i can see on our JIRA Server.  When i enable Debug/Trace logging for webhooks, the post is logged, but nothing is being sent to slack.

I also tried using modifying the URL and sending to requestb.in and still nothing.  I then setup the exact same webhook in our stage environment and it worked w/out any issues.  Is there any kind of known issue with WebHooks where they just stop firing?  I see at one point there was an issue that was fixed in 6.4 (which is the version we're running).

Anyway, I would love to know if anyone else has seen this, and if so if there is any kind of known workaround.  The ONLY log i get when i enable trace logging for the webhook, is that it shows up in the log.  But i don't see any WARNs/ERRORs etc...

Thanks!

I have the same question. The webhook posting.But not sent out to third part server. Is there a possibility that the thread pool overflows for webhook? there is some warning in log catalina.out

Jason,

Did you ever figure out what was going on? I am having the same problem and narrowed it down to something in the JQL on the webhook. We were querying on a status change and that seems to not be working anymore.
