Localhost redirects to www.localhost

Hi!

First of all, I know that there are multiple topics online related to this topic but none of them helped me. So I’m really hoping anyone of you guys can help me.

According to the Yoast SEO help stuff I changed the permalink of my localhost:8080 to https://www.localhost:8080. Now I’m unable to load my localhost wordpress page. Just the regular failure of an invalid page. I’m using USBWebserver and Chrome. Page does neither load via IE. Does anyone know how I can solve this and refix my permalink to localhost:8080?

Thanks!
