Getting "Forbidden" window when trying to open program on my Mac

I am seeing this happening to many others on the forum in the past 24 hrs. I have gone and checked through everything that has been recommended on this forum- nothing has worked. What’s the go here Zwift please?

See Internal Server Error 400 / 403 (Clear your browser)

Turn your wifi off; open Zwift. Once the screen starts loading turn wifi back on. I can’t take credit for this it’s in another thread but works every time for me this weekend.
