Have the following issue.
At business location using Comcast Business and Cisco RV042 v3 VPN router all of a sudden some HTTPS web pages will not load with error "This Page can't be displayed". This is seen in IE10, and latest Google Chrome and Firefox.
I tried to access the page and I see a Security Certificate warning and I can override and continue to site but not in above configuration. I am also using Win 7 with IE10. Tried Compatibility mode in IE 10 and other browsers but can not get to..
This is a legit govt. site and and by ###
Check a Sites Security Certificate:
SSL Certificate is not expired
Site is not listed in the certificate <-- Issue of course but hard to get a hold of someone to work this issue quickly..
Organisation details are listed
Encryption strength is at least 1024-bit
Signature Algorithm is strong Accepting only high encryption cipher suites
No connection upgrade to 128-bit for old browsers
No Extended Validation on company details
No Debian weak key present
Tried installing Root and other Certificates for this site but no help same error.
Had user connect laptop to Verizon hot spot instead of work Network (Comcast Business class with the Cisco RV042 v3 VPN Router) and the user can get the same Security Certificate issue as I see and can over ride.
Also, if they bypass the Cisco RV042 v3 router and just connect to the Motorola SurfBoard Cable Modem (SB6121) can see get to site with over ride. So, somehow the security certificate issue (root of the issue for them) is causing this the web page to do what I listed it seems. I am not seeing how the router could make it act differently (not much to configure for this area) but it is making it not even display the web page.. How???
They are now reporting a separate site (HTTPS) with very similar issue. We have not changed our network configuration at all and these sites all worked last month no issue.
So I am thinking it is part of the big Microsoft Win updates (saw applied on 11/13/13 last batch) that is somehow doing this.
Any ideas on how to proceed or what could be the cause.
The Govt. site, I listed above is: https://dibbs2.bsm.dla.mil
Other HTTPS sites work fine still.
