Hi @soEricNG. Can you provide the exact command you're attempting to execute? And what do you see when you run coder list? Thanks.

@ketang
Here is what I see with coder ls:

xiangyus/erics-template  docker-image-builds  Running  1m          false     -                     8h (in 7h59m)

I have tried both coder ssh erics-template and ssh coder.xxxx and both did not work.

I did a bit more debugging afterward, the container itself seems OK. I'm able to connect to it via the web UI's terminal and also can ssh to it from a different Linux machine. However, I just can't ssh to it from my AMD MacBook.
From my MacBook, I can ssh to the server where the coder-server is hosted, but cannot ssh to the coder's container. I have already tried recreating ssh keys + configs and ssh-add -D, but none of that worked for me, unfortunately. Wondering if you have seen something like this?

Here is the ssh log before it errors out:

debug1: Local version string SSH-2.0-OpenSSH_8.6
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535

Well, then it sounds like it's something specific to the MacBook or perhaps that MacBook's network. Do you have a VPN running or anything on the server that might selectively block certain IPs? You've covered most of the factors that vary between the non-working laptop and the working Linux box, but there may be a few remaining.

I'm going to close this for now! Our #2779 issue should track it.
