we have spotted a connection problem with GoToWebinar - Failed API connection 403 and later also error 411
The problem that we can't re-login properly (it shows error 500). When we choose the option only SAVE - connection works for a few minutes and then broke again.
We didn't change credentials or membership on GTW.
Thank you in advance for any help and advices.
I'm experiencing the exact same issue and error. Following this thread in hopes there is a solution found soon!
Same issue - reached out to Marketo support and they said that engineering was working on a fix.
