I have installed ejabberd 20.02 with homebrew (Mac OS Catalina). When trying to connect to ejabberd server with Adium I receive this error message in the ejabberd log. I am not sure how to proceed.

Error in the ejabberd log file

This looks like ejabberd is forced to use TLS/SSL on C2S connections but you did not give it a correct certificate for the host, the client is trying to connect to. One way to solve this would be to get a valid cert for your host. For example you can get them for free from Let's Encrypt. The other way to solve it would be allowing unsecured c2s connections, but I wouldn't recommend this. It could be done by setting starttls_required to false on the c2s listener as described in the docs

You can disable the TLS/SSL requirement by setting the starttls_required to false in the ejabberd.yml

listen:
  -
    port: 5222
    ip: "::"
    module: ejabberd_c2s
    max_stanza_size: 262144
    shaper: c2s_shaper
    access: c2s
    starttls_required: false
