Web App Debug mode

Hello everyone, I have a web application written with Xojo 2019r1.1 on Windows 10.
I these last days, when I run the application in debug mode, instead of setting the address http://127.0.0.1:8080 in the browser, the following string is set:
%22http//127.0.0.1:8080/"

I don’t know why, and I don’t even know how to prevent this.

Can anyone give me some advice?

Thank you!
