So, my ISP is blocking port 80... I could redirect traffic to my server using another port, but was not able to renew my Let's Encrypt certificates using HTTP-01 challenge. This is how one could use DNS-01 challenge to get/renew certificates.

First install certbot:

doas pkg_add certbot

Now ask for the challenge:

certbot certonly --manual --preferred-challenges dns --server --manual-public-ip-logging-ok -d your.domain

Change your.domain with yout domain, in my case.

Certbot will return:

Please deploy a DNS TXT record under the name
_acme-challenge.your.domain with the following value:


where aCMe-cHaLlenGe-vAluE is a string you will set on your DNS server as a TXT record value under the name _acme-challenge.

Wait for DNS propagation and press Enter.
