PowerBi Report Server Schedule Refresh Error with MySQL
i have an issue in powerbi report server while setting up schedule refresh for multiple reports, I set the connection credentials for mysql database normally and try testing the connection and everything works fine but when the schedule refresh fires i receive the below error:
SessionID: 984a1806-ce1e-4d00-b802-f94f76b496f1  -1055784932: MySQL: Retrieval of the RSA public key is not enabled for insecure connections.. The exception was raised by the IDbCommand interface.  -1055129594: The current operation was cancelled because another operation in the transaction failed.  -1055784932: The command has been canceled.. The exception was raised by the IDbCommand interface.
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.”
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.
