Hello everyone, I installed NextCloud on Docker and would like to connect and sync from the Android app. I have no problems using the browser, but the app gives an error because I don’t have an internet connection. I connect via browser from http://serverip:8088 Please help me.
try http://serverip
The IP address where I installed the server is 192.168.100.92, so I type http://192.168.100.92:8088. I don’t know if this changes anything.
I believe the NextCloud client, if not specified, uses port 80, but I have iis on that port, so I chose 8088.
Is this why syncing isn’t working? Can I set the port within the Android client app, or is there another solution? Thanks.

Unfortunatelly secrecy does not help us, to understand your configuration.
The Support Template will ask you for important information and log files, which help us to understand your configuration.
It also gives you hints to find error messages.
I don’t understand how it works. By clicking on the “Support Template” link, I find myself in a section where I should enter data and logs, but I have no way to type or paste into the fields.
What is the exact error message?
in the meantime, I attach the contents of my docker-compose and the last part of the log
the error I receive on the Android application is “upload failed. no internet connection” . it is translated from Italian so I don’t know if any words change

The Support Template first has to be copied into a posting and then filled with the needed information.
The Apache seems not to be properly configured (missing server name in the .conf file).
I set the server name in Apache, the log no longer shows errors and it started syncing, but when I turn off the internet, the syncing stops, the log changes, and the app displays the error “upload failed. No internet connection.” I use a Xiaomi Mi 10T, I don’t know if it could be due to the phone. I’m attaching the part of the log where the internet connection is turned off while uploading.
