While working on a service call in my JavaScript code that retrieves XML data using XMLHttpRequest, everything runs smoothly in Chrome and Firefox, successfully fetching the data over HTTPS. However, when attempting to execute the same code in IE11, it returns a status code of 12004. After researching this error on Google, I found one explanation mentioning that it corresponds to ERROR_INTERNET_INTERNAL_ERROR.
To further troubleshoot, I decided to observe the request using Fiddler. Surprisingly, when Fiddler is open, the service call works fine; however, upon closing Fiddler, the same error code (12004) reappears.
