articulate 360 after click sign in it show couldn't open port

Hello Nattasak!

Thank you for sharing a screenshot! 

These domains must be accessible on port 443 for Articulate 360 apps and services to work properly. Can you confirm with your IT Team that those domains are accessible?

If they are and you still see this message, I'd recommend connecting with a support engineer to look into what else needs to be configured.

Hi Amanda and welcome to E-Learning Heroes. 😊

Thank you for reaching out and letting us know that you're experiencing the same issue.

Were you able to check your allowlist to be sure that the domains are accessible as Lauren shared above? I do not see where Nattasak opened a support case with our team, so I do not have any additional information to provide at this time.

Good afternoon! I have the same problem, our IT team said that everything is fine with us. Can you tell me what to do?

Hello Oksana, and welcome to E-Learning Heroes. 😊

Thank you for reaching out and sharing that you're experiencing the same problem. Are you getting the error message that Nattasak shared above?

Here are all of the reasons that you may run into issues with signing in:

Articulate 360 Desktop App: Can't Sign In

I'd recommend working directly with our support team if you're still running into difficulty after following the troubleshooting in the article above.

I'm having the same issue - I suspect it's since the last update mid march 2022.

"Could not open a port for authentication responses."

Unable to use the software at all today

I synced my time and date on the computer clock and it started working :-) 

Glad to hear things are running smoothly on your end now, Mhairi! We appreciate you sharing your workaround in the thread for future readers!

Have a great day and happy developing! ✨
