springBoot startup log (excerpt)

paths are mapped.

but you can"t access it using ip + port number + path (for example, xxxxx:9999/xxxx). The server has nginx, running, but there is no proxy port 9999. Accessing other applications on the server is normal.

ping"s own host is also ping.

looking at your screenshot, I feel that the security group rules on Aliyun are not configured correctly. If you want to open the 9999 end, it is 999999999999

.

try accessing the server locally

 curl -vvv 'http://127.0.0.1:9999/xxxx'

see what results there are, such as local access, it may be firewall / iptables and other problems

you are right. It's a security group problem ~
