Reinstalled Mac Client and now it wont discover server

I uninstalled my Mac client via Tray Icon, reboot the Mac, removed the Mac from he server, waited until the server cleaned up the DB and then added the client on the Mac again, now the Mac tray icon is always red and wont detect my server.
Has anyone seeing similar issues? Am I missing something? maybe there is some extra cleanup that I have to do on the Mac after uninstalling the Client.

Adding something else:
I uninstalled the Mac client and reboot the Mac again, I shut down the urbackup server and did a fresh reinstall (OS and everything) , then I installed the Mac client again and now the Mac connects to the new server and started uploading backups.
Looks like, something on the server is preventing the Mac client from being added again after uninstall.
Has anybody seen anything like this? I think is important because reinstalling a whole server after months of backups are there might not be the best idea.

I’ve reinstalled OS X clients multiple times without that issue.
Are you downloading the pre-configured client from the server status page and installing from the command line as sudo?
Maybe the client is being rejected by the server. Try running the server in debug mode with urbackupsrv -v debug run
If it’s rejecting the client you will see a rejection message.

Hope that helps,

I was downloading the Mac client from the urbackup.org site directly.
Ill follow your instructions, my day is reserved for these tests today.
Do you know any way to deploy these Mac clients silently without users intervention?
I can deploy remotely to the PCs, via MSI (I have another client app on the PCs that gives me Command Line access for Powershell, bat files, etc on each PC so I can do remote installations including download app, etc),
I have the same client app on the Macs and I can also do remote command line on them, not sure if there is a way to install the client on Mac silently, directly from Command Line remotely.
Also I actually dont like the Tray Icon on Macs, on my windows PCs Im installing without Tray Icon, everything managed from the server, but I dont see option to disable tray icon on Mac, How do you do it on your side?
Thanks !

I haven’t tried disabling the tray icon, so can’t help sorry.
The way I install on OS X is to create a new client and download directly from the server.
The drop open a terminal and cd to the Download folder. Next, make the download executable, chmod +x Ur*.sh
Finally sudo ./Ur*.sh and follow the prompts adding folders for backup etc.
Sorry for the Ur*.sh, I can’t recall the exact file name.

There must be a way to perform a silent install as the OS X clients do update silently…

See e.g. here https://apple.stackexchange.com/questions/72226/installing-pkg-with-terminal

If you delete the UrBackupClient executable it shouldn’t be able to start the GUI as well…

With the sh it should be sh ClientInstaller.sh -- silent

Thanks for the tip about the Debug !!, I see a ton of stuff more now.
I see now what I see is the problem:

How does one update that access key on Mac Client?

Actually Im not sure that belongs to this particular Mac, because I have two with issues and the debug doesnt specify from which IP the error is being generated.
I also see:
2017-03-30 13:21:19: Connecting Channel to MacBook-Pro failed - CONNECT error -55
2017-03-30 13:21:40: Connecting Channel to MacBook-Pro failed - CONNECT error -55
Thats the new of the Mac im more interested on.
I will now go and remove the other one, so I make sure that im not mixing up things

Well, I removed all other clients, cleaned up the db so nothing else is there, just this one macbook pro.
I restarted urserver using debug, and rebooted the mac client.
Below is my debug output, it stays there, for more than 20 min already, nothing else is being output, but at the same time I have wireshark running on my Mac client, and every 60 seconds I see a 74 byte UDP packet thats says PING on the payload from the client to the server, and then the server replies PONG immediately after. Yes, PING PONG as funny as it sounds.
But my tray icon is still in red , even though the web interface shows “last seen” up to date for this mac client.

urbackupsrv -v debug run -u root
