Hello,

after my Let's Encrypt certificate was automatically renewed yesterday it's suddenly no longer trusted by Beagle. No settings have been changed leading up to this. Other clients, like Conversations (Android) and Monal (macOS) are connecting without issues.

The fingerprint matches the cert I see on the server. It would also be quite handy if the fingerprint was copyable from the warning to make comparison easier.

There were some changes to Let's Encrypt certificates since the last rotation where they don't include the Client Authentication EKU anymore, but to my understanding this shouldn't be relevant for c2s connections. https://blog.prosody.im/2026-letsencrypt-changes/ https://letsencrypt.org/2025/05/14/ending-tls-client-authentication
