Is this the first time you’ve seen this error and can you replicate it?: First time, reproducible
The issue you are facing:
I can’t connect with the Android app, I get the error “The server took too long to respond”.
On the web browser, after cleaning the cache and the cookies, I failed to connect at the first attempt, I stayed on the login screen for 30 seconds, then a white page showed and then back to login screen.
On the second attempt I was able to connect, but it took me more than 40 seconds to have the Files page displayed (significantly slower than when I had ownCloud 9).
I can’t connect with the client desktop (connection timeout).
I migrated directly from ownCloud 9 to Nextcloud 11 (and I can’t go back now because it took me a week to have this problem, at the beginning everything was working flawlessly 
).
The output of your Nextcloud log in Admin > Logging:
Nothing new in the log when I’m trying to connect with the android app.
Nothing new in the log when I’m connecting with the web browser (whether it’s a success or not).
Do you really wan that I copy/paste the log here?? It’s huge…
