Can't connect to standalone core-image

[Goro2030]

When running just a standalone image, with this command:

sudo docker run --rm -it --shm-size=512m -p 6901:6901 -e VNC_PW=password kasmweb/core-ubuntu-bionic:1.9.0

I can't connect just pointing an Edge browser to: http://server_ip:6901/ (server_ip is 10.147.18.72)

This is the docker log:

It is HTTPS please give that a shot and confirm

[aldobranti]

thanks for the pointer to https: protocol which allows me to proceed to a login/password dialog
I have tried kasm-user/password ( reusing the vnc password e/v )
null/null
kasm-user/null
scott/tiger ( for old times sake !)

Any ideas ?

[aldobranti]

OK kasm_user / password makes for a win!, thanks again @mmcclaskey mmcclaskey
