serveo.net returning 502 when trying to tunnel localhost web api, front-end framework angular

Question

I am having an issue with serveo.net.

I am trying to check if some Social media meta tags I introduced in my application will work properly, now I don't wish to finish a PR without being certain of the result. but since these meta tags can only be tested on a live server, I had the idea to tunnel my localhost and then check the results with https://opengraphcheck.com

my localhost is running on "localhost:4500", and I am using following command in my terminal "ssh -R 80:localhost:4500 serveo.net", this returns a URL however when I try to navigate to the URL presented by server I receive a

HTTP ERROR 502.

What could be the cause of this?

I am using back-end WEP API project built in C# and a front-end Angular project. Angular Live Development Server is listening on localhost:4500
