Seemingly overnight Oauth2 using Microsoft Azure is not working for Agents/Staff. Works fine for email fetching. When you try signing on, it just re-directs you to the home page.
Mod-rewrite is enabled and working. Nothing at all changed on the server end as far as I can tell. I've tried clearing cookies, and sessions, double/triple checked configuration, removed/re-added the plugin and set up again. Anyone have any tips? Really stumped here as it works fine for email fetching and was working perfectly fine for user/staff login but just came back today and it was broken without any visible error. If I turn on developer mode I see multiple urls being hit before the redirect.
I tried looking through multiple threads here and I see others have this issue when generically something is not configured right (E.g URL is typed wrong). Which I would love if that were the case but then I don't understand why it was working correctly in the first place and why email fetching is fine.
