Arch Linux

Description:
I've installed the latest ejabberd version which is available in the community repo (18.03-1). I've configured it accordingly, created a mariadb user + database and imported the schema from https://github.com/processone/ejabberd/blob/master/sql/mysql.sql. I've configured mysql with skip-networking. However - Ejabberd is crashing. Please find below my config and the crashing log

Additional info:
* package version(s)
18.03-1 (community repo)
* config and/or log files etc.
I've tried to get in contact directly with ejabberd; However - the forum is read only. According to their forum you have to answer a question on serverfault, which I've already done there: https://serverfault.com/questions/907724/ejabberd-on-archlinux

Steps to reproduce:

Configure ejabberd (with letsencrypt certificate + strong ciphers + mysql/mariadb backend)
Start ejabberd
Take a look onto /var/log/crash.log

Any help would be appreciated.
