Reverse proxy connection problem using android app

I configured nextcloud server and applied the certificate through reverse proxy.

For example, it’s like this.
http://192.168.0.128:8888
==>
https://mydomain:8877

Connecting through the reverse proxy in my browser works great.

However, if you connect using the nextcloud client registered in Google Play Store, an error occurs during connection.

I specified the address of nextcloud as https but
The app is trying to connect via http and is failing.
It appears that the app is trying to connect via http because it is connected via http behind a reverse proxy.

Is there any solution other than me using http instead of https?

hi @moonks830 welcome to the forum :handshake:

pleae review reverse proxy docs. Likely you didn’t add right OVERWRITE* parameters to your system config
