I am trying to set up Forge for the first time. I got an API access token from my Digital Ocean account and gave it to Forge, and now Forge is stuck on "Listening for Events." I don't know what the problems is or what to do next. It's not clear.
I had the same issue. After waiting and waiting, I refreshed the browser, only to see the same "Listening for Events" with the spinning gif. I then just clicked on the icon of one of the server providers and continued.
The confusion here is the spinning gif, which typically indicates that you need to wait while the system processes something. In my case, it could be ignored and one just continues by choosing a provider.
Hope that helps someone else who runs into it.
