TLS Handshake failed: tls: server selected unsupported protocol version 301

Grafana Cloud
1

I’m using grafana cloud for some time and yesterday suddenly with no change on my end started getting this error on all SQL queries:

“db query error: TLS Handshake failed: tls: server selected unsupported protocol version 301”

I was loged out from grafana and logged in, so maybe a new version was deployed?

Hi @dumsky,

Welcome to the :grafana: community support forums !!

That could be a reason from other multiple reasons e.g. network issues, or high latency time, DB maintenance etc.

Please try again and check if that works now.

Question: Do you have a paid subscription plan for Grafana Cloud?
