I have a website that sent an error message: "err_connection_aborted" when I connect to it using HTTPS.
When I have Fiddler active it works perfectly, so I'm not really able to debug the issue.
I've been fighting this error for several days... should be very easy, it's just a webpage under HTTPS. It works OK in HTTP, but something goes wrong with HTTPS.
Thanks!

I am a new Fiddler classic user on Windows 10. I can easily monitor http(s) requests of my browsers such as Chrome or Microsoft Edge. However, no http(s) requests are seen from my Application "Ubuntu on Windows". I have checked it (exemted) in WinConfig toolbar. What could be the problem here. Thanks in advance!

I ran a trace from a handheld device to a server in a data center. In short, the trace reads:
- ClientConnected: 12:44:55
- ServerConnected: 12:50:39
- ServerBeginResponse: 12:50:51
Does this mean that the Server spent 12 seconds data processing before responding?

this is a feature proposal. With comments made by user, we can easily trace back the session after saving lots of sessions.

The url captured by fiddler can send instructions through the software's own composer and return the correct json file.
However, the correct result cannot be obtained under the requests of python, and it will prompt:
{"Message":"Cannot convert object of type \u0027System.String\u0027 to type \u0027Carpa.Web.Script.HashObject\u0027","StackTrace":" in Carpa.Web.Ajax.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer)\r\n at Carpa.Web.Ajax.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)\r\n at Carpa.Web.Ajax.AjaxHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary `2 rawParams)\r\n at Carpa.Web.Ajax.AjaxHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
The code is as follows: ("..." means omitted information, the headers are consistent with the information in the fiddler software)
from urllib import response
import requests
import json
url = "http://......Web.Script.DataService.ajax/GetPagerDataEx"
headers = {
"Accept":"*/*",
"Referer":"...",
"Accept-Language":"zh-Hans-CN,zh-Hans;q=0.8,en-US;q=0.5,en;q=0.2",
"Content-Length":"...",
"Content-Type":"application/json;charset=utf-8",
"X-ClientType":"SLJson",
"X-JSONFormat":"true",
"Accept-Encoding":"gzip,deflate",
"User-Agent":"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.2; WOW64; Trident/7.0; .NET4.0C; .NET4.0E; Tablet PC 2.0)",
"Host":"...",
"Pragma":"no-cache",
"Cookie": "...",
"Connection": "keep-alive"
}
data = {
"pagerId":"$......$ptypeDataSource",
"queryParams":"null",
"orders":"null",
"filter":"null",
"first":"...",
"count":"...",
"isFirst":"false"
}
data = json.dumps(data)
response = requests.post(url=url,data=data,headers=headers)
content = response.text
print(content)
Hope that helps, thanks!

I am completely new at this fiddler thing and I have no idea what it does. I just know that I can't connect to anything without having fiddler on otherwise it just keeps loading and says I cannot connect to the internet. I used it to find a value in a game and I am stuck using fiddler to just gain access to the internet. I uninstalled it and everything and it will not go back to the way it was. I want nothing to do with this program anymore I just want my pc back for everyday use without having to launch fiddler every time to connect to discord or steam or the internet etc. I have tried checking and unchecking "capture https CONNECTs" many times. I have reset all certification multiple times. I have also went in a deleted all the ones from fiddler and nothing changed. I also know if I don't use "act as system proxy on startup" I cannot access the internet. Thanks.
