Can you do some experimenting with openssl s_client?
openssl s_client -connect ipv6 -servername dnsname server:993
see if this triggers it?

The only modification in the configs I sent is to shorten the domain names and IPv6 prefixes. Is there anything else I should’ve attached?
A full repro would require TLS certificates and keys too.
Thanks, Jan

Hi!
I see this intermittent error with my dovecot setup.
The most puzzling part is that it sometimes works and sometimes rejects connections, spitting out the log I attached in systeport (DNS).
I am binding both ipv4 (TLS+SNI) and ipv6 (dedicated addresses). TLS certificates for corresponding DNS are shared across ipv4 / ipv6.
Thank you, Best regards, Jan
Any chance you could send set of config files that reproduce this issue, or your original config files?
