It's rare, but some users use wildcard certs for inter-node TLS. We should document the correct way to configure Erlang for this scenario.

Not only for inter-nodes. There is a lack of documentation for federation plugin too.
How to connect to a remote SSL cluster which have wildcard in SAN certificate ?
I tried to pass the following (properly url-encoded) setting in URI parameters :-S :

{customize_hostname_check, [
        {match_fun, public_key:pkix_verify_hostname_match_fun(https)}

@cvuillemez in your case you are currently out of luck, and the solution is to not use wildcard certs.
