I’ve been having a strange issue signing in on iOS devices. I have a newly-created Nextcloud setup with a NGINX reverse proxy in front. When I try to sign in to the iOS app using my password, I see “Access Forbidden Invalid request.” When I try signing in via token, I only see a white screen with the close button – No error message. The interesting thing is when I look at my HTTP logs, I can see perfect HTTP 200 status codes being returned and the device shows up in settings, so it looks to be a bug with the iOS app. However, I have an old Nextcloud setup that works just fine with the iOS app, but this one does not have a reverse proxy nor HTTPS. (it was behind a VPN)
- This indicates that there is a problem with the reverse proxy. Which mistakes could cause this and what should I check for?
- Where could I locate logs for the Nextcloud iOS app which would seriously help my debugging process?
