Gateway timeout while trying to connect to DB

I am getting 504 timeout when connecting to my DB.
It may be blocked by my provider.
What is the ip from which all the requests from Grafana goes (

Hi !
Could you show please telnet to you DB host on DB port (I guess it standard 3306) from your grafana server.
Command :

telnet db_hostname 3306

The Grafana is hosted on your cloud server, how can I do a telnet from it?

I’m not from grafana support. I’m just customer. I have installed the grafana on my own server and I thought that you have your own server like me.
So in this case just wait answer exactly from grafana support or try to contact with your provider
