    So I have been driving myself nuts for the past two weeks. I have a windows XP network and VPN setup with a few computers running some POS (Point of Sale) software. All of a sudden out of the blue my POS Software stopped processing credit cards giving error 53 failure to communicate to card processor. The POS software is called Cash register express by PC-america uses Internet Explorer to process the transaction. I called my credit card processor and they said to go to the following website to make sure there is not a firewall restriction Https:// SO this is where it all gets screwy In internet explorer I cannot reach that website or any other website that has a https redirection like or If I use Chrome or Firefox I can reach the sites just fine. I have tried all IE recommendations like enable tls 2.0 resetting defaults making sure no proxy servers are setup and clearing ssl certificates. I have a feeling its DNS related because I have a a location that is connecting via VPN on a different ISP and it is running the same exact build of IE and its working just fine. If I turn on my hotspot and connect with a wifi adapter it goes to the HTTPS sites just fine.
    I have a Cisco rv325 VPN router I have set Google DNS
    I have a Verizon Actiontec Modem I have also tried Google DNS and DNS verizon Recommends.

    I'm running out of things to try. It really seems that something in Verizon modem is blocking https on the old IE 8

    @ George:-

    I really doubt it's got anything to do with your router. It's more likely to be Internet Exploder itself, always was a piece of crap.

    Have a look here:-

    Some of this might help.....especially answer #4. You ought to look into whether it's possible to set-up the transaction processing in another browser. It would make the entire process more secure, as well as considerably smoother...
