That's not the right URL convention for a Meeting in Connect. Additonally, https://nccor1.adobeconnect.com just throws a 404 error for me. So either there is something is incorrect about the server URL or the account has been shutdown or disabled. This isn't the normal error you see for a mist typed URL, so I'd think that something should be addressed by the Adobe Connect Support Team. It looks like all services are up and running, https://status.adobe.com/products/3011
Normally a Meeting URL won't have the API or index component. It would be nccor1.adobeconnect.com/meeting. Changing the nccor1 to an account I know is working just results in a Not Found page from Connect, which is what I would have expected. So, I think that to better understand what your issue is, we'd need more context about why you ended up using that URL path and how that account is supposed to function since it appears to be non-standard.
