Hey !

Your certificate expired today, I can't access it because of my business proxy :).

[No Error] (TLS code: X509_V_ERR_CERT_HAS_EXPIRED) SSL Certificate expired on: Jan 2 06:31:02 2024 GMT

Maybe you have the old certificate cached somewhere. I see the doc.dovecot.org site returns a certificate with valid dates that seems to have been renewed a month ago.

openssl s_client -connect doc.dovecot.org:443 ... Certificate chain 0 s:CN = doc.dovecot.org i:C = US, O = Let's Encrypt, CN = R3 a:PKEY: rsaEncryption, 2048 (bit); sigalg: RSA-SHA256 v:NotBefore: Dec  3 06:29:22 2023 GMT; NotAfter: Mar  2 06:29:21 2024 GMT ...
