The issue you are facing:
Since upgrading to nc18, it seems I have an issue getting the android app to work via my configuration with HAProxy (on my pfsense FW). Every time I try to upload something via the app I get SSL initialization failed. Going to NC via the browser works fine and shows no errors. If I bypass the HAProxy via the app it works as well.

Is this the first time you’ve seen this error?: Y

Steps to replicate it:

  1. Configure HAProxy as a reverse proxy with SSL offloading
  2. Try to upload a file

Did you check your SSL configuration with ?

All good with an A+ score.
I did see a couple of posts regarding a setting for the ecdh curve and that it needs to be set to prime256v1 but no matter how I tried to configure it on the HAProxy, nothing seemed to worked.

I have this exact same problem and have not found a way around it so far. I too get an A+ score on the SSL testing sites, but the Android app will not upload files. NextCloud 23.0.0
