This issue has been fixed. Backups no longer stop after a short wait with "host server unreachable". Larger backups run in the background and show as pending until they finish. If a backup failed during this time, please simply create it again.

The fix has been rolled out. Large backups now run in the background and show as pending until they finish. We are monitoring whether backups complete again. If a backup failed for you earlier, please start it again.

Cause found: the nodes are reachable, but the platform only waits 10 seconds for a backup to finish. If it takes longer, the misleading "host server unavailable" message appears. We are working on a fix. Your running servers are not affected.

Creating backups for game servers and bots currently fails with the message "The host server is currently unavailable". We are investigating the cause and whether other actions are affected.
