It is the issue with chrome not an issue of the firewall you will be able use Microsoft Edge and Mozilla Firefox and it will work.

There is a workaround you do for chrome:

Open registry editor and go to the following path:
>HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome

> Right-click and > Add a new DWORD (32-bit) Value ,Changed the Name to RSAKeyUsageForLocalAnchorsEnabled and set the value as the default (00000000). 

Close chrome and open again. You can reach out to to google through google support form for editing the key usage field and also check with your Certificate authority.
