Why codespaces add a extra port in the address?

Question

I am using Codespaces and I would like to know why if I run an Spring Boot Web application, running on port 8080, if I click in the link when I redirect port the address add an extra ":8080"

https://codespaces-name-8080.app.github.dev:8080/home

But it should be:

https://codespaces-name-8080.app.github.dev/home

Many thanks in advance

This address: https://blog.cloudflare.com/super-bot-fight-mode/ is going to the default HTTPS port, which is port 443. You said your Spring Boot app is running on port 8080. Port 8080 is not the default HTTPS port, so the port has to be specified in the URL: https://codespaces-name-8080.app.github.dev:8080/home
