HTTP Login Credentials for Docker version

Hey
after running Docker version of playSMS , none of the usual credentials seems to work,
I ran

docker pull playsms/playsms
docker run -d -p 81:80 playsms/playsms

the following dont work

admin/admin
admin/changemeplease

what am i missing?
thanks

I see that it works when I run in my local docker, but when I run on a server it doesn’t work
