Hi Andy,
This seems like a server issue and is probably related to your server instance, more specifically an issue with 2FA. Have you checked the server logs?

Please raise an issue on https://github.com/nextcloud/server

Hey! This only happens with the iOS app every other app works fine?

[mpivchev]

Hi, we can reproduce a similar issue internally. I will update you once I have more information.

I thought that either:

• [stable31] fix(base.php): Correct order for booting \OC\Server server#51371 (part of unreleased 31.0.2, but a workaround was merged in 31.0.1)
• or [stable31] fix(login): Properly target public page with attribute server#51295 (part of 31.0.1)

fixes it? Can you try patching it?

Fix is available here: nextcloud/server#51544
