Hello All,

Hi @msafey ,


If you are a new MySQL user with Power BI, be sure to create a username within the database and execute a “GRANT PRIVILEGES” command for the username to give it read permissions.


During my investigation, I found that some users solved this problem using the following

“You should add client option to your mysql-connector allowPublicKeyRetrieval=true to allow the client to automatically request the public key from the server. Note that allowPublicKeyRetrieval=True could allow a malicious proxy to perform a MITM attack to get the plaintext password, so it is False by default and must be explicitly enabled.” 


For more information,you can refer to this .


Hope it helps,

Hello caitlyn,

how can i add allowPublicKeyRetrieval=true in PowerBi?


Hi @msafey ,


My bad, this seems to be used for other mysql connectors, please try referring to the link in SU's first reply and see if that method fixes your problem. I can't help any farther. I have not meet this problem before and cannot reproduce it,  looking forward to having another expert in RS to solve your problem.
