I have two nextcloud servers I connect to with my client. With one of the servers the client keeps going offline. if I quit the client and restart it immediately connects to both servers, but after some time one of the servers goes offline. if I go to that servers web interface it immediately comes up. the server is run as a docker client and if before checking the web interface I check the docker container it shows as running.
I’m not sure what information/logs I can get from the windows client.
