My Broswer Firewall (Not Secure Https) not enabling ArcGIS for Portal to reload and restart...
Hi Okeke,
What you're seeing is expected behavior as part of the installation process for Portal for ArcGIS. Next, you need to install the ArcGIS Web Adaptor and configure it with your Portal. You will also need to enable HTTPS on your web server. See this help topic,
Install ArcGIS Web Adaptor—Installation Guides (10.5) | ArcGIS Enterprise
Hope this helps,
