Unity Hub will not let me log in to my account on my work network

I have posted this before and just wanted to see if there was an update. I can't submit a bug report on the hub because the "Server is unresponsive". Also it seems others are having same problem. I can log into my account with the latest version of 2018.4.6. But when it comes to the hub, it won't let me log on and gives me the previously mentioned message. I am an instructor and want to start using Unity 2019 but do not want to start until this problem gets solved. I also contacted our IT Dept and told them to add the following to our firewall exceptions:
HTTPS://accounts.unity3d.com
HTTPS://api.unity.com
HTTPS://license.unity3d.com

They did and still can't log in. When I load 2019.2 I can also access the package manager which is weird. Any help is appreciated.

Here is what I posted before:

In Unity 2019.2, under the account button, the sign in is grayed out...can't access it. In 2018.4,,,it's not grayed out and I can sign in...

 

We use Windows Defender Security Center on our PCs and I think the firewall hardware is from Palo Alto Networks...don't know if this helps. And, I added firewall exceptions on my PC.

 

@safaGH...thanks for your response. I do have the latest version of the hub.

 

Messaged some of the log...perhaps this needs to be added to our firewall whitelist? https://core.cloud.unity3d.com/api/users/me
