I have a jQuery ajax POST that sends data to the server and immediately I get a ::ERR_CONNECTION_RESET message in the console:
POST http://www.example.com/casino/update net::ERR_CONNECTION_RESET
In the browser Network tab, the request shows this

There is nothing in the Preview or Reponse tabs
In the error callback, the error object contains the following:
{"readyState":0,"responseText":"","status":0,"statusText":"error"}
... so it's not very apparent what the issue is.
Here's the code
$.ajax({
url: this.action,
type: this.method, // always POST in this case
data: $(this).serialize(),
dataType: "json",
beforeSend: function () {
toolbar.SaveButton.startLoaderIcon();
},
complete: function () {
toolbar.SaveButton.stopLoaderIcon();
},
success: function (result) {
toolbar.SaveButton.stopLoaderIcon();
SettingsPage.renderResultMessages(result, "Casino", null, null);
//update Casino Operating Systems table with saved data
reloadCasinoOperatingSystemDataTable(result.CompatibleOperatingSystems);
reloadTrackerLinksDataTable(result.TrackerLinks);
reloadCasinoGameTypeDataTable(result.CasinoGameTypes);
reloadCasinoBankingProvidersDataTable(result.CasinoBankingProviders)
},
error: function (error, type, httpStatus) {
toolbar.SaveButton.stopLoaderIcon();
var message = "The Casino was not saved because the following error occurred:<br />" + error.status + ' ' + error.statusText + ' - ' + httpStatus;
SettingsPage.renderErrorMessage(message, "Save Error");
}
});
This only seems to happen to me - not to any of my users. It happens in Chrome and Firefox, so doesn't appear to be a browser issue.
Again, this only happens to me, so it can't be a server or header issue. When I debug locally on localhost:[portnumber]/... it works fine, so it does not appear to be anything to do with the app
Thanks in advance
UPDATE:
- I tried everything described here
- I tried deactivating all extensions in Chrome
- I tried on two other machines on my network with success (so it's my machine!)
- I tried turning off every feature in Norton Security and turned off Windows Defender
- I turned off Nord VPN
- I read about 73 SO posts that mention ERR_CONNECTION_RESET
- I even tried in Edge!
Only remaining variable seems to be Windows 11 (the other two machines are Windows 10)
UPDATE 2: I tried Wireshark to check for network traffic and followed this turorial but it seems that a network connection is not even being established. Ajax GET requests work fine...
UPDATE 3: Uninstalled Norton Security Ultra and rebooted. Same sh**. When I view one of my photos on photos.google.com and hit SHFT+D to download it, I get "ERR_EMPTY_RESPONSE".
