Hi all,
after upgrade to 2.4.4 along with all packages upgrade we are unable to connect to two very important websites.The message displayed is:
Error
This page can't be displayed due to blocked resources . Contact IT support for additional information
The incident ID is: N/A.
The Event ID is: xxxxxxxxxxxxxxxxx.
NSlookup is fine for both websites. Also if i connect my pc directly to the router bypassing pfsense, the websites load fine. How can i troubleshoot what is going on?
