Remote redis queue?

A project is running on 127.0.0.1. 222.222.222.222 is running on the server. Originally, 1000 queue requests were sent locally to the local redis queue A. When A1 is completed, B1 of the queue B, local listen, and so on. The queue is successfully completed. The local 127.0.0.1 is running a project. 222.222.222.222 is running on the server.

Originally,
Send 1000 queue requests locally to the local redis queue A. After A1 is completed, start B1 of queue B, local listen, and so on. The queue is successfully completed.

Now,
1000 queue requests are sent locally to redis queue A on the server. When A1 is completed, B1 of queue B is started, local listening is performed, and so on. However, after 7 or 8 requests are executed, the listener will throw a php.exe timeout exception and end the listener.

Why?
