S2S connection between two ejabberd's fails

[wornet-mwo]

The problem is based on connection between two hosts.

What version of ejabberd are you using?

17.12 in both setups

What operating system (version) are you using?

alpine, both setups based on the docker image ejabberd/ecs:17:12, running on ubuntu-docker-host

How did you install ejabberd (source, package, distribution)?

ejabberd/ecs:17:12 from hub.docker.com

What did not work as expected? Are there error messages in the log? What
was the unexpected behavior? What was the expected result?

S2S connections fail from both sides. The receiving side logs this:

The connecting side:

Connections from other domains servers (non ejabberd) are working.

Maybe related settings:

´´´
s2s_use_starttls: optional
´´´

Additionally on CCC.de:

acl:
  good_s2s_peers:
    server:
      - "YYY.net"
      - "jabber.YYY.net"
acccess:
  s2s:
    good_s2s_peers: allow
    all: deny

I'll provide additional config etc. anonymized on request (as there is a customers system involved) and this is quite hard to do in advance. Thanks in advance for help.

Clearly installation problem: some bytecode files are missing.

[cromain]

mix.exs lacks xmerl application

[cromain]

xmerl is used only to call xmerl_regexp:sh_to_awk/1. maybe this can be rewritten to avoid need to include all xmerl by the way.

[cromain]

fixed by 3df78d3. We removed xmerl dependency.
