Cannot connect to file provider service INTERNAL_ERROR

[d1nd141]

Hi,

i can't connect to my own hosted nextcloud instance.

Error i receive: Cannot connect to file provider service stream was reset: INTERNAL_ERROR

Other apps (Win Sync, IOS etc are working fine through the nextcloud app/file provider)

Maybe the issue is that i'm using a dedicated port & path

https://www.xyz.com:12345/cloudxyz/

Certificate is OK, so webdav. An nginx reverse proxy is in front of nextcloud, while nextcloud runs in a docker container.

There are absolutely no logs on nextcloud nor nginx while connecting to nextcloud instance. Using tcpdump i can see traffic coming in to the dedicated port configured.

2FA is disabled.

I tried to connect with and without url scheme. Connection tried using Samsung Tab S6 and Oneplus 9P.

Could you please help?

Thanks

Edit: Using the filepicker and using the nextcloud file works fine.
