I disabled Redis and put N8N in regular mode, it worked perfectly, then I deleted the Redis volume, ran it again and returned N8N to queue mode and the problem started again, the requests on the endpoint enter the queue and do not leave, they do not execute. Is there a problem in this version using N8N in queue with Redis. In version 1.78.2 this was not happening.

My setup uses docker-compose and also a Redis queue. It’s probably not due to the new version. In Queue Mode, there is usually a separate N8N Worker instance running. Can you see anything in the logs of this worker?
I found the problem. The command variable was set to the same value.
# comando padrão para subir o servidor web do editor
command: start
# comando padrão para subir o servidor web do editor
command: webhook
# comando padrão para subir o servidor web do editor
command: worker --concurrency=10
