Cannot create channel sink to connect to URL
From Array Suite Wiki
Very rarely, users would see error saying: "Cannot create channel sink to connect to URL' tcp://18.104.22.168:1234/RemoteServer'. An appropriate channel has probably not been registered."
This happens when there's a tinny typo in the LandExplorer.cfg file, i.e. tcp:/22.214.171.124:1234.
or there's an extra SPACE between WebServerUrl= tcp://192.168.3.113:8075
Double check the LandExplorer.cfg file, make sure it follows the standard template, then the issue should be solved.
