Dump-config looks correct:

./notify_push --dump-config config.php

    redis: [

}

It seems to be as if the tools tries to establish an TLS connecion over the local unix socket what does not make any sense.

Using 127.0.0.1 as DB host also doesn't work (failing with InvalidDNSNameError what is correct, using the hostname in the server certificate doesn't work too with the very same error "received corrupt message"),

How can the ssl_mode config be controlled?

System:

• Debian 10.9
• DB: MariaDB 10.3
• PHP 8.0
• ./notify_push --version: notify_push 0.1.7

Got the same error here. Using the binary from #83 https://github.com/nextcloud/notify_push/actions/runs/793350027 and the IP for the database instead of the hostname solved the issue, but it would be nice to have an extra option to turn TLS off for the database connection.
