Difference between various SCRIPT7002: XMLHttpRequest: Network Errors

Question

There is a plenty of SCRIPT7002: XMLHttpRequest: Network Errors around. And I, as many others, also struggle to understand the meaning and the root cause of my errors (00002efe / 00002ef3 in particular).

Just a few of similar errors that I came across:

SCRIPT7002: XMLHttpRequest: Network Error 0x2f7d, Could not complete the operation due to error 00002f7d.
SCRIPT7002: XMLHttpRequest: Network Error 0x2ee7, Could not complete the operation due to error 00002ee.
SCRIPT7002: XMLHttpRequest: Network Error 0x2efe, Could not complete the operation due to error 00002efe.
SCRIPT7002: XMLHttpRequest: Network Error 0x2ef3, Could not complete the operation due to error 00002ef3.
SCRIPT7002: XMLHttpRequest: Network Error 0x2efd, Could not complete the operation due to error 00002efd.
SCRIPT7002: XMLHttpRequest: Network Error 0x2eff, Could not complete the operation due to error 00002eff.
SCRIPT7002: XMLHttpRequest: Network Error 0x2f76, Could not complete the operation due to error 00002f76.
SCRIPT7002: XMLHttpRequest: Network Error 0x2f78, Could not complete the operation due to error 00002f78.

I would like to learn whether there is a resource (documentation) that explains the difference between these various error codes and what their meaning is.

Any information would be much appreciated.

Answer 1

Ok, I think I found the answer. This solution certainly doesn't cover every single code but it gets me the info that I was looking for.

Here are the steps that I took:

Step 1 ) (in Win) open calculator and switch to a programmer mode.

Step 2 ) Select the "HEX" option in the calculator

Step 3 ) Copy the error code from the message. (the error starting with zeros eg 00002efe)

Step 4 ) Paste the error code to your calculator.

Step 5 ) Change to "DEC" option.

Step 6 ) At this point, you have the decimal value of the error. I have found two websites that describe the meaning of these error codes. Now, head to one of these web pages:

• https://support.microsoft.com/en-us/help/193625/info-wininet-error-codes-12001-through-12156

• https://msdn.microsoft.com/en-us/library/aa385465.aspx

This is what I got as a result of my searches:

00002f7d => 12157 > ERROR_INTERNET_SECURITY_CHANNEL_ERROR
The application experienced an internal error loading the SSL libraries.

00002efe => 12030 > ERROR_INTERNET_CONNECTION_ABORTED
The connection with the server has been terminated.

00002ef3 => 12019 > ERROR_INTERNET_INCORRECT_HANDLE_STATE
The requested operation cannot be carried out because the handle supplied is not in the correct state.

00002efd => 12029 > ERROR_INTERNET_CANNOT_CONNECT
The attempt to connect to the server failed.

00002eff => 12031 > ERROR_INTERNET_CONNECTION_RESET
The connection with the server has been reset.

00002f76 => 12150 > ERROR_HTTP_HEADER_NOT_FOUND
The requested header could not be located.

00002f78 => 12152 > ERROR_HTTP_INVALID_SERVER_RESPONSE
The server response could not be parsed.

Hopefully, this will be handy to somebody.
