Yesterday, the UrBackup Docker app for TrueNAS changed from Version 1.1.10 to Version 1.1.11.
This has some relevance to me, because as soon as the app was updated, one of the hosts on that subnet was finally discovered by the server and is now getting backed up. The issue had been the subject of a weeks-long pursuit of what might have been amiss, during which I received a significant amount of help and guidance from @LJ_LongWing.
The 1.1.11 update didn’t change UrBackup itself. It only updated TrueNAS’s shared app library (the code that turns the app settings into the container config). The UrBackup server image is still the same 2.5.x build as before. Release notes for the TrueNAS app are only in the commit history of the truenas/apps repository on GitHub.
My guess is that what helped was the update recreating the container, so the server restarted with fresh network state and found the laptop again. If it stops finding a client again, restarting the app is worth trying first.
