Server created and running - not accepting 123456 verification code :C

Hello I followed the Docker setup instructions all the way through and my server is up and running.
I have setup the android app with| Manual server address. I Also selected Accept any SSL certificate I then tired to Register and put in the Verification code ( 123456 ) and it says " Verification code refused " .

Any help would be great I have not made any changes to the but the line : sess-man/plugins-conf/network-domain= ( I switched this to my domain name. ) As I wanted my server to be private.

Debian 9 x64

Hello! Could you post your server log please? At least the part concerning the error.
