It is safe to trust this certificate, BUT the implications are that you will not see any genuine certificate errors from websites, so you should keep Fiddler closed when you're not using it, and you should remove the certificate if you stop playing Neopets games.Fiddler seems to

Answered on 26 Mar 2020, 01:40 PM Hi Chinh,This could be caused by a network configuration. Let me provide some troubleshooting steps below.1. Ensure the machine running Fiddler can communicate with your Android device. Find the Android IP Address by going to Settings -> About Phone -> Status -> IP address. Then ping the Android device from the Fiddler machine using a command prompt.- If the device is unreachable, the result will look like below. - The following screenshot is what the result will be if the device is reachable. 2. Ensure the firewall on the Fiddler machine is properly configured and that Fiddler has been restarted after enabling remote connections. Additionally, upon enabling Remote Connections in Fiddler options, the notification from the below screenshot should appear. After enabling remote connections and restarting, try pinging again.- Note that in the prerequisites of the referenced blog post, it states that Kamen had to connect the PC to the Android device's tethered network in order to get it to work. If the device is still unreachable at after enabling remote connections, I recommend tethering the PC to the Android device's hot spot.3. If the above options still do not work, Network and Discovery may need to be enabled on the Fiddler machine. See the How to Enable Network Discovery on Windows 10 blog post for how to do this.4. Finally, if nothing works, there could be a configuration on the router that is blocking peer-to-peer communication which happens on some enterprise networks.. Configure Fiddler / Tasks.

Free fiddler 4 Download - fiddler 4 for Windows - UpdateStar

I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed.Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through Tools>Options>Settings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor. Configure Fiddler / Tasks. Using Fiddler.
