    error solved successfully by adding tls

    const imageQueue = new Bull("imageQueue", process.env.REDIS_TLS_URL, {
  redis: { tls: { rejectUnauthorized: false } },
});

    bull uses ioredis to connect, and allows a third opts parameter in the Queue constructor. According to the source code it looks for a redis property within those opts.

    You might try this to raise the retry limit to 100.

    const opts = {redis:{maxRetriesPerRequest:100}}
const imageQueue = new Bull("imageQueue", process.env.REDIS_URL, opts);

    But, also, you may be using Heroku’s redis service more intensively than they allow for the free tier (if that’s what you use).
