The password used in the connection between client (PRTG sensor) and server is send in a hashed format.

For this to work properly, client and server need to use the same hashing algorithm.

The original hashing algorithm used by MySQL (prior to 4.1) has been deemed to be unsecure. Version 4.1 implements a new hashing algorithm, where the sensor is apparently still using the original hashing algorithm.

The server complains about this by sending the error "Authentication with old password no longer supported, use 4.1 style passwords"

To allow the database to accept the old style hash you can run SET old_passwords=TRUE
