   Thanks for the report, and sorry the Go plan has been so slow for you.

   OpenCode 1.19.4 is part of v1 (the opencode-ai package). v1 now only gets fixes for critical bugs, so this is unlikely to be fixed there. Please try the current v2 release (the @opencode/cli npm package, which provides the opencode command) and see whether the slowness and the EPROTO: The TLS handshake failed errors still happen.

   If they also happen on v2, or you think this is critical (for example the process really crashes with no workaround), please reply here with:

   • the v2 version (opencode --version)
   • the Go model you used
   • a debug log excerpt from opencode --print-logs --log-level DEBUG that covers a slow or failing request
   • whether a proxy, VPN or corporate network is involved

   Please also try once without oh-my-openagent so we can rule the plugin out.

   If this turns out to be a problem with the Go service or your subscription itself rather than the app, email [email protected] and keep account details out of this public issue.

   We haven't heard back, so we're closing this as not planned. The report is about OpenCode 1.19.4 (v1). v1 only gets fixes for critical bugs, and slow Go plan responses with intermittent EPROTO TLS handshake errors don't fall into that category.

   If you still see this on the current v2 release (@opencode/cli), please open a new issue with:

   • the v2 version (opencode --version)
   • the Go model you used
   • a debug log from opencode --print-logs --log-level DEBUG that covers a slow or failing request
   • whether a proxy or VPN is involved

   If it's a problem with the Go service or your subscription itself, please email [email protected]. Thanks for reporting it!
