Tell me if any additional info is needed, thanks

This should be the intent behavior. There is an option --retries, where is tells the service how many retries to connect to the remote server. If it cannot connect, it exits. If systemd has to restart the service too many times, it deactivates it. We can add an option to not exit.

Hi, yes i managed to workaround this by doing this override to the doh-client.service to force systemd to restart it endlessly

[Unit]
StartLimitIntervalSec=0
RestartSec=1

Having an option to set --retries -1 for endless retries could be useful
