Moved servers, 
and every Gemini capsule started screaming "untrusted server."

Why: my old server (agate) only does self-signed TOFU certs, no CA chain and clients had the old fingerprints pinned, so they rejected the new ones too.

Fix: patched gmnisrv to send a full Let's Encrypt chain, forced TLS 1.3, and fixed a crash where a big chain overflowed the handshake buffer (a free DoS on a public port). Renewals auto-reload now.

Patched fork: https://git.virebent.art/virebent/gmnisrv

Live, CA-verified, TLS 1.3:

- gemini://n5ry24fweklbn562o7fnyefanygtwxlgi7aevn26huuxqlsftxy5ljqd.onion (self-signed —

If your client grumbles once about a changed cert, accept it. That's TOFU.

Best regards and have fun !
