JavaScript获取请求错误：无法加载资源：net :: ERR_CONNECTION_RESET

Question

So I've been developing my application for a while now, and didn't encounter such an issue until recently this afternoon, when starting application after some changes in the javascript code I got an error while loading a request from server side like this:

In the console I am writing readyState and status, and the first two values happen as soon as web page is loaded and other ones come after like 5-10s time out. This is the code that is supposed to be running.

 window.addEventListener('load', function() { let xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { console.log(this.readyState); console.log(this.status); if (this.readyState === 4 && this.status === 200) { GetGoals(JSON.parse(this.response), goalsList); } }; xhttp.open('get', '/api/mainmenu', true); xhttp.send(); }); 

I am starting my application on the file and running it on the chrome. While I googled i found some answers talking about certificate mismatch, but why would that happen only after some time? How could i solve this issue? I am developing on .NET Core asp.net 2 and vanilla js.

EDIT: It seems that only this get method fails, post method works fine which is even stranger.

Answer 1

Okay, so the issue was different from what I imagined. There was an issue with my SQL Servers. It seems that i might have turned off one or it got turned off somehow and it could not get the request to the database, which is strange indeed.
