Website redirects wrong -> DNS
-
From today, I'm unable to open a Prezi (working yesterday). It's blank and gives an error. They claim it has to do with possible security or firewall settings.
Strangely, when I try to view their support forum, I'm getting an odd 404 page. Instead of viewing the forum, I'm "redirected" to a BrandYourself profile with underneath the 404 "this profile does not exist". The URL is not redirected, but it doesn't load the requested page.I'm having exaclty the same problem with Ricoh E-Services, exactly the same page (Brandyourself unexisting profile). This happens on all computers in our LAN.
This is the forum that doesn't load correctly: http://getsatisfaction.com/prezi
This is an example of the brandyourself 404 I'm seeing instead: http://thisdoesnotexist.brandyourself.com/ (url is http://getsatisfaction.com/prezi though)I'm using Unbound without forwarding mode. Changed DNS on the gateway from 8.8.8.8 to OpenDNS but still the same problem. Restarted Unbound already.
Didn't do any config changes between yesterday and today.I just found another website with similar problems:
Lastpass.com: NET::ERR_CERT_COMMON_NAME_INVALID
Subject: *.brandyourself.com
Issuer: Go Daddy Secure Certification Authority

Current date: 3 mrt. 2015nslookup lastpass.com -> 38.127.167.48 & 128.121.22.133 gives same cert error as above
nslookup getsatisfaction.com -> 54.244.244.251 & 54.244.125.70 & 50.112.98.44 same -
Enable the DNSSEC related hardening options in unbound and stop forwarding to OpenDNS that does not support DNSSEC at all. Preferably, just stop forwarding (period).
