We develop a web application for internal use at our client sites, and it relies heavily on ajax requests. We have 20+ clients nationwide, many of whom are on the same version, and most with a high volume of users.
At only one client, we are seeing our ajax calls fail relatively frequently with status 12031 (ERROR_INTERNET_CONNECTION_RESET right?). "Frequently" meaning 0-10 times per day, whereas other clients of similar use/volume rarely ever, if at all, see this error (we log everything).
We can't seem to reproduce this, and are pretty sure it's due to their internal network flaking out. Are there any good tools or code we could use to analyze why this might be happening, and possibly figure out a recommendation? I doubt we'll be able to change, or even view, any router settings as we are just one small application on the massive internal network.
Thank you in advance!
