PRTG connector connection issue - ERROR EXECUTING REQUEST: Method failed: (/api/table.xml) with code: 401 - Invalid username/password comboIssue Post Configuration of PRTG connector and mapping with credentials, when the Test Connection is executed the connector shows status as Error status with the below message. Connection test failed: ERROR EXECUTING REQUEST: Method failed: (/api/table.xml) with code: 401 - Invalid username/password combo TypeError: Cannot read property "0" from null Check point from our side: CauseThe issue is observed with the Password used for configuration.ResolutionIn order to resolve this issue, please check below: The username should be defined in the Login name in the PRTG system (in the user management screen)The password field value needs the passhash value from PRTG. This is a hashed password value, and not what was originally entered as plaintext into PRTG.Note: see the PRTG manual for finding the hashed password https://www.paessler.com/manuals/prtg/my_account_settings If there are no users in the PRTG system (in the user management screen), you should define one. After making the above changes, the connector started working without any issue.
