Can't access external MySQL database from render istance

Hi there!
I was trying to deploy a python script that has to connect to a MySQL server, but it gives me this error:

mysql.connector.errors.DatabaseError: 2005 (HY000): Unknown MySQL server host (host):3306’ (-2)

I’m sure the host is correct, because i tried to connect to it via localhost and it worked, if you can help me solve this issue i would be very greatful! (i replaced the hostname with ‘host’ for privacy).

Hi there,

Can you provide more details of the host you were trying to connect to? If you would prefer to keep these details private, please open a ticket directly with us using our dashboard.

Regards,

Keith
