Answer 1

The domain name cannot be resolved and you need to find a domain name resolution service...

ping www.xxx.cn 或 nslookup www.xxx.cn(windows) Check whether the domain name resolution is obtained

Answer 2

Same as above, the domain name cannot be resolved and it has nothing to do with nginx configuration
