I added these days two more clients which has already 12 working clients.
The first one went well and the first backups are already done. The second was added (tried it twice) is running on the client machine, but on the server the status is “ok” and online shows no.
I checked also the firewall / port settings together with hosting provider to be sure that none are closed.
After re-installation I get only this warning in the client’s log file:
WARNING: Shutting down (Signal 15)
Where do I have to look further?
The client is installed on Ubuntu 18.04
