Docker – Ports are not available: listen tcp 0.0.0.0/50070: bind: An attempt was made to access a socket in a way forbidden by its access permissions

I faced the same issue and I didn't want to change the default port of MSSQL (1433)

Here what I did to fix this problem.

Make sure that your port is not in used, Go to resource monitor to validate this. Now check if the port is reserved. Open your command prompt and enter this

netsh int ipv4 show excludedportrange protocol=tcp

The port listed here are managed by hyper-v and the only way to remove the port 1433 here is to disable hyper-v, reserve the port 1433 so hyper-v doesn't reserve it back.

Disable hyper-v

dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

Reserve the port 1433

netsh int ipv4 add excludedportrange protocol=tcp startport=1433 numberofports=1

Re Enable hyper-v

dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All

Start docker and run your container

-p 8080:80 says "forward port 8080 on the host to port 80 in the container". Port 80 is determined by the container image. Port 8080 is arbitrary—it's a port you're choosing.

So instead do -p 8081:80, and now you point your browser at localhost:8081 instead of localhost:8080.

If that doesn't work then maybe it's your firewall?

(See https://pythonspeed.com/articles/docker-connection-refused/ for diagrams of how port forwarding works).
