Hi, I’m back with something getting wrong ☹ I enable monitoring and get this error msg like the title. I try the different with such as reinstall PMM, Everest. But still stuck in bug, yesterday I still works but in the morning, I cannot monitor db instance run on the Evest anymore. ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/3/3c1b2b3f93705744d864c90e678e1f369446fe7c.png) It looks like the credential wrong, but in step added the monitoring endpoint, it success and create a apikey in pmm. ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/d/d5eb63727833f6b81ba8c19c6d58463ed086f935.png) ---

Hi @just3tee I’ll need some more information to understand what’s happening. Which DB type were you testing? MySQL, MongoDB, PostgreSQL? Which version of PMM server are you using?
