Hello,

I just installed tlinc on RHEL 8.5, and I am able to connect to the master management webpage (localhost:1010) but sadly it says that the master is not running.

The following error message is displayed:

System Status  
Error  
Internal Error: Traceback (most recent call last): File “/opt/thinlinc/modules/thinlinc/tlwebadm/status.py”, line 323, in \_vsm\_call Ooo0O00o = self . \_vsm\_connect ( ) File “/opt/thinlinc/modules/thinlinc/tlwebadm/status.py”, line 304, in \_vsm\_connect IiiI1III1iI = Ooo0O00o . create\_user\_socket ( 0 ) File “/usr/lib64/python3.6/xmlrpc/client.py”, line 1112, in **call** return self.\_\_send(self.\_\_name, args) File “/usr/lib64/python3.6/xmlrpc/client.py”, line 1452, in \_\_request verbose=self.\_\_verbose File “/usr/lib64/python3.6/xmlrpc/client.py”, line 1154, in request return self.single\_request(host, handler, request\_body, verbose) File “/usr/lib64/python3.6/xmlrpc/client.py”, line 1187, in single\_request dict(resp.getheaders()) xmlrpc.client.ProtocolError: \<ProtocolError for 127.0.0.1:9000/RPC2: 404 Not Found\>

I’d be grateful if someone knew what is what. Thanks.

Hello,

Where is that stacktrace displayed?

You’d have to investige why vsmserver service fails to start, i.e investigate  
journalctl -u vsmserver and look in /var/log/vsmserver.log for clues on why it failed to start.

Best regards,  
Martin
