503 Service Unavailable appears on the website

Question

After using Xiaoniao Cloud Server to build a website, what does it mean when the web page displays 503 service unavailable? How to deal with it?

Answer 1

You can try it with the iis7 server monitoring tool. If the website exceeds the system resources, increasing the number of IIS connections can solve the problem.

Answer 2

Errors starting with

5** indicate that the error comes from the server side. It is difficult to judge or locate the error based on this prompt alone. Please describe in detail what you want to do? What you have done, as well as the requested script code, etc.
