Run the docker but always show connection reset?

[loik7754]

I would try to run the docker image on Ubuntu 18.04 and start normally, but when I use the browser connect to the webpage, it always shows "Connection Reset".

I'm sure that the firewall enables port 5050 and changeth start.sh form 127.0.0.1 to 0.0.0.0 still cannot connect to the web page.

My OS: Distributor ID: Ubuntu Description: Ubuntu 18.04.5 LTS Release: 18.04 Codename: bionic

Docker Ver: Version: 20.10.2 API version: 1.41 Go version: go1.13.8 Git commit: 20.10.2-0ubuntu1~18.04.2 Built: Tue Mar 30 21:24:16 2021 OS/Arch: linux/amd64 Context: default Experimental: true

Please help me with anything I mistake? Thanks a lot!
