 found the questions they asked before on the Internet: 
 1. Some said it was configured in php-rpm.conf, but I did not find the corresponding file in whereis search in the server 
 2. Some people said that it was a node problem, and individual nodes abroad could not access 
. Anyway, they did not give a specific solution
