When I turn fiddler on every http call is a 502 access denied issue. Everything I've googled indicates it's a proxy/firewall issue. As the attached image shows, the only proxy I'm using is the default fiddler proxy. I have windows firewall turned off but Kaspersky Endpoint protection is turned on but I don't think this is the problem because I checked with a coworker and he has no access problems and we're under the same policy in Kaspersky. I've struggled with this all day and have not been able to isolate the issue even though I've gone through all the different settings. Does anyone have any idea or can point me in the right direction here?
