Parse Live Query sometimes doesn't trigger Create, Update event

Thanks both for kind help @dblythy @Manuel , will it be the similar to this post? How could I check the redis server works for this configuration? Since I reviewed my redis server, seems no new DB or data created there. My redis server co-used as bull (GitHub - OptimalBits/bull: Premium Queue package for handling distributed jobs and messages in NodeJS.) queue.

And, from the official document, it tells url shoul be like this:

redis://localhost:6379

while my redis already created 16 DBs, or should I define the url similar as below?

redis://localhost:6379/1
