Upgrading UMP to 8.47 fails with login error
The setup installUMP.exe for upgrading UMP 8.31 to 8.47 reports following message:
"There was an error logging in. Verify that your credentials are correct for the specified hub."
The error message was actually somewhat misleading.
The cause was found by debugging InstallAnywhere which gave a better log showing
Error logging in and getting the hub robot IP: (80) Session error, Unable to open a client session for 127.0.0.1:48000: Connection refused: connect
- Localization lookup: [Key=UsernamePassword.Error] [Value=There was an error logging in. Verify that your credentials are correct for the specified hub.]
The entry "Unable to open a client session for 127.0.0.1:48000" points to a problem with IP configuration rather then user login
The problem could then be resolved by enabling Local IP validation on the robot (activate the button "Check configured IP against list of known
local IP address")
To view or capture the debug output from a InstallAnywhere installer, you need to hold down the <CTRL> key immediately after launching the installer until a console window appears.
Before you exit the installer, copy the console output to a text file for later review.
