And look around some other github isues that mention getting a 401.
I am running php-fpm 7.2
Apache 2.4.37
HAProxy Loadbalancer
Nextcloud 16.0.1
I have tested current Stable and Beta branches of Nextcloud Android app. (It also happens in IOS App)
And as i said before, Nextcloud login works every time when I use a Browser, the App is what fails to log me in every time (and gives me the 401 and Login Loops)
