Unable to establish connection to https://www.arcgis.com/

[luckachi]

I am trying to start Pro on one of our machines and I keep getting an "Unable to establish connection to https://www.arcgis.com/" error. I stumbled upon this article but I don't even get a sign in screen

Any help would be appreciated as some of our public facing tools are not working.

Hey @luckachi 

Would it be possible to restart the machine? It may be a DNS or DHCP issue on the machine side that could be stopping it, I would try using the command prompt to ping "www.arcgis.com" and see if it hits properly as well.

I restarted the machine this morning and no change. I will try the command prompt ping right now

Hey @luckachi 

Thank you for testing this out! Since the ping goes through you can connect which is good! I would try giving Pro a soft reset like this here:ArcGIS Pro Soft Reset 

After this, my only other suggestion would be to reinstall ArcGIS Pro, then contact Esri Support, could you also attach a screenshot of the connection error?

Thanks Cody! Appreciate your help with this - I will try the soft reset and see what happens.

Soft reset didn't work 😞 but I noticed that the StrongName folder doesn't exist in my local folder (even after the restart ). Will be following up with ESRI support.
