   Thanks for the detailed diagnostics. Comparing with curl made this easy to place.

   I think this is a duplicate of #60399. Your pattern matches it exactly: OpenCode 2.x gets ECONNRESET on https://opencode.ai/console/api/v2/config, while curl to the same endpoint and the same IPs gets a normal HTTP 401. The cause found there is network traffic filtering (DPI) that drops or resets the TLS handshake (ClientHello) sent by OpenCode 2.x's bundled runtime. That handshake includes a post-quantum key share, which makes it about 1.5 KB. curl's handshake is much smaller and gets through. The connection is cut before any HTTP request is sent, so the client never sees the 401. A mobile hotspot often doesn't help, because mobile carriers in the same region can filter in the same way. In the related reports, a VPN or a DPI-bypass tool fixed it. Ensure the tool covers opencode.ai, models.dev and registry.npmjs.org. #60399 has more measurements and workarounds.

   Closing this as a duplicate of #60399, since there's been no reply showing a difference. Your symptoms match it: OpenCode 2.x gets ECONNRESET on https://opencode.ai/console/api/v2/config, while curl to the same endpoint and IPs gets a normal HTTP 401. Both point to network filtering (DPI) dropping the larger post-quantum TLS handshake that OpenCode 2.x sends.

   Please follow #60399 for updates and workarounds. In related reports, a VPN or a DPI-bypass tool covering opencode.ai, models.dev and registry.npmjs.org fixed it. To have the team confirm your Go Plus subscription, email [email protected]. If a VPN doesn't fix it, or your problem turns out to be different, reply here and we can reopen.
