Problem with Portainer

Hello, I hope I found the right place to get some help. I have a problem with mineos running in portainer, I can’t acces the webui. Docker/portainer is something pretty new for me so please no hate if I have something obvious done wrong.
So I installed the container over portainer, made the portforwarding for 8443, everything seems to work but the web-ui not, from chrome I just get the error “ERR_EMPTY_RESPONSE”

I hope somebody can help me :slight_smile:
