Ejabberd 21.12 SSL Certificate

[AndreyKaO]

OS: Astra Linux Special Edition
Ejabberd: 21.12

Good time of day. We deployed Ejabberd with the conversejs module, there was a problem connecting to the site, you need to make exceptions for our domain. Is there a 100% instruction for obtaining an SLL certificate. After trying the instructions from the Internet, 90% do not work.
Connecting by https://domain:5443/chat (conversejs).

What does the error message say in english?

Any errors/warnings in ejabberd.log?

[AndreyKaO]

Что в сообщении об ошибке написано на английском?

Какие-либо ошибки/предупреждения в ejabberd.log?

The connection to the site is not secured

[licaon-kter]

Ok, so the cert is the issue.

Now, HOW did you get the certificate? certbot? dehydrated acme client? acme.sh? ejabberd ACME client ?

[AndreyKaO]

Entered this command

openssl req -newkey rsa:2048 -nodes -keyout domain.key -out domain.csr
And passed the questionnaire

[benniledl]

Try this:
cat /etc/letsencrypt/live/domain/privkey.pem /etc/letsencrypt/live/domain/fullchain.pem >> /etc/ejabberd/ejabberd.pem
then add /etc/ejabberd/ejabberd.pem to the yaml configuration file
