I’ve been using Comodo Secure DNS for quite a while now. Recently, I find that this site ( https://wiki.mozilla.org ) will give me a failure to load “no server found”. I thought it was the site having problems. I set my system to obtain a DNS server automatically and now I can load the site with no problems. I got no “Comodo” warning from the Secure DNS, just the browser saying it couldn’t find the server. This happens with IE, SeaMonkey and Firefox.
Does the problem still happen when you flush DNS cache while using CSD?
When it still happens consider reporting it in Report Blocked Sites You Believe Are Safe Here
I just flushed my DNS cache according to your first link. I re-enabled CSD and the page loaded fine. I’ll give it a couple of days to be sure the problem is gone. If it reappears, I’ll use your second link. Thanks!
Well, that didn’t take long. The page has returned to its “not loading” state. I’m off to file a report!
