Rediss:// connection returns error

[melishev]

Current Behavior

I'm trying to connect to my Digital Ocean hosted Redis database using this configuration:

RedisModule.forRootAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: async (configService: ConfigService) => {

        return {
          readyLog: true,
          config: {
            url: 'rediss://default:<password>@<host>:25061',
          },
        };
      },
    }),

I take the connection string from DO, and it is correct. But when I try to connect, I get an error:

var err = new errorClasses.AbortError(error_attributes);
                      ^
AbortError: Redis connection lost and command aborted. It might have been processed.

I believe this error is related to SSL/TLS connection and configuration

Context

Sorry if my problem is stupid or already solved. I am new to Redis

@melishev Unfortunately, I have no credit card to create Digital Ocean managed redis instances.
For testing purposes, you can try to connect to your redis instance via redli or RedisOptions(use ioredis directly) like this:

redli --tls -h redis-test-do-user-4915853-0.db.ondigitalocean.com -a your_password -p 25061

const Redis = require('ioredis');
const fs = require('fs');

const redis = new Redis({
    host: 'hostname',
    port: <port>,
    tls: {
        key: fs.readFileSync('path_to_keyfile', 'ascii'),
        cert: fs.readFileSync('path_to_certfile', 'ascii'),
        ca: [ fs.readFileSync('path_to_ca_certfile', 'ascii') ]
    }
});

FWIW, I did not have this problem with this package using just Redis commands. However, I did have this problem when using @nestjs/bull. I found this solution on the main bull repo: OptimalBits/bull#1464 (comment)

So you might try:

RedisModule.forRootAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: async (configService: ConfigService) => {
        return {
          readyLog: true,
          config: {
            redis: {
              tls: {},
              connectTimeout: 30000,
            },
            url: 'rediss://default:<password>@<host>:25061',
          },
        };
      },
    }),
