Thanks for the report! It looks like
opencode pairfails while creating the remote-access tunnel: the TLS handshake withhttps://opentunnel.xyzfails withunknown certificate verification error. The certificate on that host verifies correctly from our side, so we need some details about your setup to reproduce it:@opencode/cli, install script, Homebrew, …)opencode pair?)NODE_EXTRA_CA_CERTS,HTTPS_PROXY)?curl -v https://opentunnel.xyz/andopenssl s_client -connect opentunnel.xyz:443 -servername opentunnel.xyz </dev/null | grep -E 'Verify|i:'show on that machine?You can reply here with the details 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.
I didn't find an existing report of this tunnel failure. These related issues show the same TLS error in other places, ordered by likelihood of being related:

We haven't heard back about your setup, so I'm closing this for now. The certificate on
opentunnel.xyzverifies correctly from our side. Without your OS, how you installed OpenCode, and your network setup (proxy, VPN, custom CA), we can't reproduce theunknown certificate verification erroryou got fromopencode pair.If it still happens, please reply here with those details and the output of
curl -v https://opentunnel.xyz/, and we can reopen it. Thanks for the report!
