Not working a background job with using Resque on Heroku-Twitter bootstrap

I have my rails application that has a job (using Active Job). I use resque and resque-scheduler gems for queuing backend.

I want to connect my rails application to a redis-to-go server with Resque on Heroku but I get many error messages on my logs, like this:

2019-12-01T12:04:00.942767+00:00 app[worker.1]: resque-scheduler: [INFO] 2019-12-01T12:04:00+00:00: Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)

2019-12-01T12:04:04.004590+00:00 app[worker.1]: resque-scheduler: [INFO] 2019-12-01T12:04:04+00:00: Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)
2019-12-01T12:04:05.012344+00:00 app[worker.1]: resque-scheduler: [INFO] 2019-12-01T12:04:05+00:00: Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)

Everything works on development and production environments, but doesn’t work on Heroku. I found many questions with a similar problem, but their solutions didn’t help me.

I get an error message Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED) from redis gem in the establish_connection method. But when I figure out the necessary values from rails console, I understand there is OK.

$ heroku run rails console

Moreover, I understand that the settings for resque and resque-scheduler gems work correct after restart my application on Heroku, but for some reason Resque connects to localhost:6379 instead of a redis-to-go server. Have you any ideas, why this happens? And how I can solve this problem?

I have provided the necessary information about my settings, using gems, etc below.
