element-ios Unrecognised Request

Steps to reproduce

We have been using a school server in our school for several years, which supports a messenger according to the Matrix standard. Logging in with riot and later Element always worked without any problems. If I now want to log on to a mobile device (primarily iPadOS), the error "unrecognised request" appears. Existing logins can still be used without errors. The error does not occur with desktop apps.

Outcome

What did you expect? Login

What happened instead? No login, „unrecognised request“

Your phone model

No response

Operating system version

@kknigge-sbs Can you provide us with more information in order to reproduce this issue? If the homeserver is public that would be useful, otherwise

What is the server configuration like (Password only, SSO, multiple auth flows)?
When does the alert appear (after entering the server address, a specific screen when registering, on tapping continue on login?

Element Messenger fails with the first request "displayname", which is acknowledged by the server with a 400. Then it tries again dozens of times.

FluffyChat on the other hand uses other requests which are executed successfully. FluffyChat can then be used successfully.

The collected server information and log extracts of both apps can be found in the attached file. Parts of the requests were anonymized, recognizable by the often repeated letters in a row. It should still be sufficient for analysis.

Nothing is logged in the Messenger's Homeserver.log for the two attempts.
