PRTG connector connection issue - ERROR EXECUTING REQUEST: Method failed: (/api/table.xml) with code: 401 - Invalid username/password combo

• 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: 

• The issue is observed with the Password used for configuration.

• In 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.
