GoToWebinar Integration issue
Dear all,
We are facing a weird issue with GoToWebinar: the connection fails with an erro 403.

Following a couple of posts from the community, we have tried to re-log in to GTW, to no avail. a pop-up window opens with some error messages, but it's too quick to be able to read the error messages.
We have tried to recreate a new connection, but the result is the same.
GTW documentation says that there will be some change in the API base URL: Important Account Updates. Normally, the deadline is supposed to be Dec 2017, but could this be the issue ?
Has any one else had the same issue?
