"Record" site does not open, prompting 118 error, network connection failure problem

This morning, I have several stations are not open, are prompted 118 error, network connection failure do not know how to do?

The first is to use a ping, found that the network connection problems, some areas of the ping does not come out, and finally appeared 502 hints.

1. Start 118 connection error, estimated due to server network. Finally normal, and the result of 502 errors

2. nginx Submission This problem Linux architecture Lnmp Ask a lot of 502; ( if it's a station problem, it could be a program issue.

, you have to say that all the stops are a problem, and that's your overall architecture . visual, you php-fpm. Nginx is not connected to the back end)

3. I restarted all the server's service ports on the VPS management software, and then the website returned to normal.
