The "512 worker_connections are not enough" error with worker_connections 65535;
in the configuration suggests one of the following:
- Either the configuration in question is not used. Make sure you've reloaded the configuration after changing it. Make sure you are editing correct configuration file - the one that is used by your nginx instance. To make sure consider adding a deliberate syntax error to the file and check if nginx refuses to start.
- Or you are using a third party module which tries to open connections in a helper process. Consider checking "nginx -V" output and your configuration to make sure you are seeing the problem without any 3rd party modules.
If unsure, please provide full "nginx -V" output, and full configuration (full "nginx -T" output). Please also provide details about the process which reports errors ("ps -ef | grep nginx" output and some recent "worker_connections are not enough" errors).

512 may not be dynamic
Want it to prompt
"65535 worker_connections are not enough"
Thank you very much.

The worker_connections
can be reconfigured dynamically, though you have to instruct nginx to reload the configuration. Please see comment:2 for suggested steps on how to understand what is wrong in your particular configuration.
Multiple servers, the same specific is 512
Year-on-year test
Same server, same configuration
1.16.x no such problem
Thank you very much.
