Hi Team, I am currently doing POC on airbyte and have deployed latest Airbyte Version: 0.40.17 on Docker version 20.10.20, build 9fdeb9c When i am trying to setup MySql source i am getting "The connection tests failed." in frontend UI. I could see below error logs from airbyte-proxy container logs airbyte-proxy | 2022/11/08 085113 [error] 13#13: *1 upstream timed out (110: Connection timed out) while reading response header from upstream, client: *.*..*, server: , request: "POST /api/v1/scheduler/sources/check_connection HTTP/1.1", upstream: "http://***.*..*:80/api/v1/scheduler/sources/check_connection", host: "localhost:8000", referrer: "http://localhost:8000/workspaces/68ef7d91-b53e-48a9-a40e-64cd63aa3cf2/onboarding" Can someone help me out here

connection timed out usually mean airbyte cannot reach your database, did you try opening up a firewall rules or actually going onto the airbyte instance (vm?) and attempt to connect to the mysql instance from it? i.e:

telnet [ip_of_mysql_instance] 3306

If you get a mysql connection message connectivity is good, if you don't then it's not able to reach it and you need to fix that.

@Alexandre Voyer Thanks🙂 Firewall is blocking MySql port.
