KB5016623 Issues with AAD App Proxy
Hi Andrew,
We had the same issue today. Uninstalling KB016623 resolved it as well. I've logged it with Microsoft. Will report back when they respond.
Glen.
freddy104 MS has advised not to patch the server until fix is released. They proposed a registry change, however it did not work.
Word from Microsoft is that this issue is fixed in the November 8 Patch Tuesday patches. Can anyone confirm if they have tested the 11/8 patches to confirm the issue is resolved?
- Installed Nov patch for Server 2016 (kb5019964) and appears to have resoled the issue.
Similar patch for Server 2019 is KB5019966:

I just wanted to jump in here, even though it's an old thread, and let you know that you're not alone. Others have reported similar problems. One suggestion I've seen is to try using individual proxies for specific tasks. This might help isolate any potential conflicts that could be causing the crashes and authentication problems. You can check out https://proxys.io/en for more information on setting up individual proxies.
