But when I used my container’s dns name and port number from an external browser, I received timeout error:

http://mydockerapp.centralus.cloudapp.azure.com:8080/

Steps to reproduce the behavior

Installed docker
Ran “docker run -it -p 8088:8080 --rm tomcat:8.5” comman

Solved my problem.
I was running it on a Linux VM and that server needed port 8080 to be whitelisted for incoming HTTP requests for TCP port 8080. Allowed that and it worked next time.

Thanks
