Error "Socket fail to connect to host:localhost, port:xxxxx

Get Help
1

I use docker image metabase/metabase:v0.35.3 with postgres:9.6-alpine. When just start up and configurate a datasource via ssh, it’s running smoothly. But after a period of idle time, I would get the following errors. I think the connection pool of metabase can’t perceive the ssh connection idle timeout, so it still use the existing connection. So should I optimize the parameter of connection pool and how? Thanks.

Hi @linhonghui
I think you’re seeing this issue, which says the workaround is to setup the tunnel manually instead of using the builtin tunnel in Metabase:

There’s also another problem using the builtin tunnel:

Thank you for your reply and I think it is different scenario. It is ok between metabase and configuration database(I use postgres). The error I met is metabase can not access the remote datascource(mysql) via ssh after a period of idle time with no operation in metabase. So I think it caused by the ssh time out (about 2 minutes). Maybe should optimize the parameter of connection pool of metabase for access datasource and it is similar to C3P0(maxIdleTime, testConnectionOnCheckin, idleConnectionTestPeriod etc.).

Any body can help me?

I’m having the same issue here. Metabase is running on a Docker, there is a SSH Tunnel with a private network to the MySQL Database.
I can connect successfully, read the tables, some data, but after some time the connection is broken.
“Socket fail to connect to host:localhost, port:43461. Connection refused (Connection refused)”

Did you found any solution?

Tks

@isslerman I think the only solution would be to create the SSH tunnel outside of Metabase.

Same issue we are experiencing but there is no help:

Socket fail to connect to host:localhost, port:42016. Connection refused (Connection refused)

Hello every,

I have the same error
I have set my external MySQL database with ssh tunnel (with GUI Metabase interface) on default port 3306 and I can connect successfully, read the tables, some data, but after some time the connection is broken. When I try to read the tables I got “Socket fail to connect to host:localhost, port:35678. Connection refused”

NOTE I not set port 35678(every time I got a different port in the message error) in setting I set default port 3306.

Anyway, If I go to admin panel and go to my set MySQL database and click “Save” without any change that I can read the tables. But after same time ago the error appear again and again

Tell me how to fix this and how can I create a permanent tunnel for Metabase?
and even if I find how to create permanent ssh tunnel what if i wanna setting 2+ more external databases?

@Dmitrii You are likely seeing this issue:

The workaround is to use a manual SSH tunnel outside of Metabase:
