Hello,

I have problem with my rocket.chat auto SSL Let’s Encrypt - it is working only on private address.
I have redirected ports 80 443 and 3000. On public address it is working only on 3000 via http.

Https on 443 shows:
PR_END_OF_FILE_ERROR

I installed it from SNAP and used autossl. OS is Ubuntu 20.04.
Also, I have correct DNS records: in LAN chat.mydomain.com is resolved as private IP, and public DNS resolve chat.mydomain.com as address wtich im redirecting to.

Also, when I use in CaddyFile tls self_signed https is working on public (after redirect) and private address on default 2015 port.

I dont see anything in logs…

Any ideas?
Thanks.
