This would be better placed in the ArcGIS Pro‌ space.  Have you checked your Internet Explorer security settings?

Make sure the Use TLS 1.2  option is checked...

Just having the same problem, is anyone can point me the solution one more time? The old thread is an expired link.

I actually find the solution somewhere else and since the original solution link expired. I will put some quick steps for whoever might need this:

This most likely a windows machine only problem and you will need to go the IE browser (no edge, chrome, or firefox) --> Tools --> Internet Options --> Advanced --> Scroll down to the check the Use TLS 1.2 option --> restart the ArcGIS Pro
