For a while (about 6 months) I had no problem. All HTTP requests appeared on Fiddler https://social.technet.microsoft.com/Forums/systemcenter/en-US/00f7a091-03e0-4952-a9b4-147d485a3059/http11-502-proxy-error-connection-refused-nvia-11-tmg01-spnconnection?forum=Forefrontedgegeneral and so on. The last two days Fiddler stoped working :/ Always returns the same error: "The request failed with HTTP status 502: Proxy Error ( The ISA Server denied the specified Uniform Resource Locator (URL). )." The strange thing is that only happens to my application, i. e. all HTTP requests from youtube, email, etc, appear on Fiddler. What is the problem here? asp.net fiddler isaserver share|improve this question edited Dec 20 '11 at 19:21 JayC 5,84921733 asked Dec 20 '11 at http://stackoverflow.com/questions/8580487/fiddler-error-502-proxy-error 18:55 rpf 1,47162742 Did you install an ISA/ForeFront server in the last two days on your local machine? Any Antivirus/Malware/Firewall software? –Alexander Galkin Dec 20 '11 at 19:00 No, nothing installed. –rpf Dec 20 '11 at 19:02 Microsoft's corporate network hits this; it occurs when the proxy server denies bounce-back to prevent IPSEC circumvention. Without Fiddler running, change IE's proxy settings to "Automatically detect settings" then restart Fiddler. –EricLaw Dec 22 '11 at 13:47 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote I had the same issue with Fiddler - my HTTPS site worked fine in IE, however got 502 error in Chrome. After analyzing the issue, I found that has manual proxy enabled in Fiddler (not recommended): Tools -> Fiddler Options -> Gateaway it was the root cause of this strange behavior. Switching to "System Proxy" made this working for both IE and Chrome. share|improve this answer answered Feb 25 '15 at 8:31 udalmik 4,3031330 add a comment| up vote 1 down vote I had a scenario where production url was https and test was http. When wrongly calling test with https in fiddler then I got 502 and ended here on stack overflow. I will just leave this here in case anyone else does the same mistake. share|improve this answer answered Jan 13 at 9:10 Thomas Koelle 505717 add a comment| up vote -7 down vote accepted I solved my problem =) I
