Sorry this hasn't been picked up yet. The log shows new
serve --serviceprocesses failing every ~16 seconds, which usually means a service is already running but the new launch can't reach or recognize it. Could you tell us:%USERPROFILE%\.wslconfigon Windows (especiallynetworkingModeandautoProxy).env | grep -i proxyinside WSL. If proxies are set, doesNO_PROXY=127.0.0.1,localhost opencodestart?opencodejr commentedon Oct 28, 2026
Thanks for the logs! Each
serve --serviceattempt fails because something already holds127.0.0.1:49375and it isn't an OpenCode service the CLI recognises, so it keeps retrying. To find out what is holding the port, could you reply to the earlier questions from @neriousy and also add:opencode service get. 49375 isn't the default port for the release channel (49374), so we'd like to know whether it was set by hand.cat /proc/sys/net/ipv4/ip_local_port_range ss -ltnp | grep 4937%USERPROFILE%\.wslconfig(especiallynetworkingMode), and whether OpenCode Desktop or the Windows CLI is running at the same time.As a test, you could also try a port below 32768, e.g.
opencode service set port 28894, then runopencodeagain and tell us whether it starts. With WSL mirrored networking, Windows and WSL can reserve ports that look "in use" even though nothing is listening on them.You can reply here or edit the issue. If you edit it, please also leave a comment saying you've updated it, so we know when you're done.

We're closing this for now because we haven't heard back. To find out what is holding port 49375 in WSL2, we still need the details asked for above: whether it happens on the latest 2.x release (newer versions name the process holding the port in the error), the output of
opencode service get,cat /proc/sys/net/ipv4/ip_local_port_rangeandss -ltnp | grep 4937, and your.wslconfignetworking mode.In the meantime, a port below 32768 may get you running, e.g.
opencode service set port 28894.If it still happens, reply here with those details and we can reopen it. Related: #55907, #55918.
