Application error

my game won’t open. the message appears:
Application Error
The connection to the server was unsuccessful.
(https://localhost/index.html)

How to fix it?

Reinstall, if you’re using an specific version you can get it from here

thank you but same problem. :frowning:

I have the same problem. We had reported the bug but for the moment I haven’t had a solution.

I am using version 5.1.147. I tried uninstalling and reinstalling but it didn’t fix this problem.

Same here. Latest version of GDevelop.

Fresh install message appeared then exited. Subsequent load runs fine. Odd.
