I'm working with flask, redis and rq-worker in my web application that is hosted ina debian 9 machine. When I start rq-worker I get this error: "Error 111 connecting to localhost:6379. Connection refused".

I already checked if Redis was installed and running, I tried these comands:

/opt/apps/mywebapp/flask$ ps aux | grep redis
sib       4987  0.0  0.0  12784   976 pts/2    S+   09:37   0:00 grep redis
redis     6574  0.1  0.0  40860  3512 ?        Ssl  may28   3:38 /usr/bin/redis-server 127.0.0.1:6379

/opt/apps/mywebapp/flask$ redis-cli ping
PONG

I've read other post and this is an evidence that Redis is running and woking.

I also check the file redis.conf and I set this variable:

bind 127.0.0.1

I tried again.

/opt/apps/mywebapp/flask$ rq worker

But I keep receiving the error.

Error 111 connecting to localhost:6379. Connection refused.
