Opencode "unable to connect"

[shaftoe]

Description

Since last Homebrew upgrade it seems that opencode can't connect to the internet (workstation connectivity is definitely ok), seems related to bun not being able to install @opencode-ai/plugin, see logs below.

It might be related to my specific host but I'm signalling anyway because it seems that the error is not really surfacing to the user properly, the editor opens and accepts commands but just says it can't connect to some unspecified URL:

OpenCode version

1.0.207

Steps to reproduce

$ opencode --print-logs --log-level DEBUG run "update AGENTS.md"

How did you solve it? I've encountered the same problem.

@ChenKun1997 what version r u on?

1.0.152

[rekram1-node]

@ChenKun1997 upgrade to latest think this was fixed awhile ago

[ChenKun1997]

@rekram1-node I have updated to the latest version 1.1.4, but the problem still exists.

[rekram1-node]

@ChenKun1997 is it retrying? If u see it stuck retrying u have some type of network or proxy that is blocking the request and thats an issue on ur end

@ChenKun1997 I'm using Little Snitch (firewall) and it somehow decided to block networking for the newly installed opencode version, I removed the offending blocking rule and it did the trick.
