Cannot port forward using helix app

Each time I attempt to add a port forward it gives me this: We're having some trouble

No matter what I do it gives me that error message, I don't know what to do anymore, same problem persists 12 hours later. Is there something wrong with my router?

Edit: I was somehow able to add a port forwards but the port still isn't open even if it says otherwise in the app

And if i try to add any other port it gives the same error message
