from the previous week to now, I found a problem: when the whole network accesses the url address, it always gets stuck somewhere, and the page cannot be loaded. Later, F12 called up the console and found that there was an abnormal js file access. At that time, it was debugging a personal blog deployed on its own server. All the js and css files in the personal blog are stored locally on the server (39.107.xxx.xx is my server IP, because the domain name is still on record, so I use IP to access the transition directly)

but unexpectedly found a request for js outside the chain: http://116.31.119.212:2048/jsqz?s=39.107.xxx.xx/static/js/bootstrap.min.js?tid=00ad15545818&rid=3b81d37c3935 status:faild type:javascript

browser version: Google browser has been updated to the latest version (10th anniversary version)
and then I have the intention to take a look at other websites. After visiting all the other sites, large and small, the general card owner will not come out, but the ctrl+F5 will be normal once, and the request will disappear.

the first time I encountered such a situation, I felt too weird and uncomfortable. At first, I suspected the problem of the js file on my server. I changed the js file of jQ to a mirror image of Baidu. The file access of jQ was not abnormal, but the js of bootstrap began to visit outside the chain again. In the end, though? The latter parameter is directed to the correct address, but it is always failed!

is it:
A virus in a computer? The browser was hijacked? DNS problem? Problems with local cache files?

PS, A few days ago, I found out through the search engine that the IP address belonged to a server called 5T computer room. IP, called their service number to see if they were clear, but the person who answered the phone said it was not their business.
