Build cluster failed


When I start the node by docker ,it show msg like this. What’s the problem here, or how can I find the detail error somewhere? thanks

Hi @lgt

This appears to be a networking issue on your side, relating to memberlist.
Here is an issue which appears related to your question, with some debugging instructions:

Thanks for help, I think is not the network problem , because all the firewall is closed ,and I have try to ping from each node and it’s ok. Could you please give me more advice , thanks~
Here is my config.yaml:


and my docker-compose.yaml:
image

Pings will only tell if your network can pass around ICMP packets; this is unrelated to what your problem is here.

Did you follow the debugging steps provided in that issue?
Are all the required ports accessible, etc?

I have tried telnet 7946 and it’s ok. Is there any more required ports I need to test?

And how can I debug it because loki is running on the server. I’m not familiar with the programing language in that issue show. I guess it’s like a timeout fallback?
