    hey Alexander, thanks for such a quick response, i am a big fan of Fiddler, been using it since 7 8 years now i think. 

    So i took the upgrade, now it doesnt show the exception, and gets me the cert thats good but

    what i did was, upgrade fiddler, added certmaker plugin from fiddler plugin list, then reset certs from fiddler settings, (got new certs from cert maker) then went to my ios device, got new certs from ipv4.... well i cant even access google now, it just redirects connects and thats it, plus cant decrypt as well. 

    all this from ios device, pc browsers working fine with fiddler, Any help would be appreciated.

    Give my regards to Eric if you can! He is a genius ! :)

    Hello,

    Did you trust Fiddler's Root certificate on the iOS device? If yes, do Fiddler capture any traffic at all (HTTP, HTTPS Tunnels)? Also, what version of iOS are you using?
