I have successfully logged in to Integration Cloud (https://integrationcloud.talend.com).
No I am trying to connect via Talend Studio for Cloud with same credentials and default Service URL (https://integrationcloud.talend.com/ipaas-services/services/inventory)
When testing connection i keep having same problem: Problem with connection to Integration Cloud.
Should i user some other Service URL?
I know this is an older post but I am experiencing the same issue with 6.4.1. I am able to connect to the TIC portal in a browser window outside of the application and there is no firewall, in addition my firewall is disabled while testing.
I'm currently facing the same issue with TIC Hybrid Edition 6.3.1, have you solved the issue by any chance or still have it?
For some reason I found that the Service URL was changed in my TIC, I changed it back to "https://ipaas.integrationcloud.talend.com/ipaas-services/services/inventory" and it worked fine.
