"Invalid protocol" when trying to connect to Elasticache Redis in Node.js

[cmgchess]

Hello

I'm trying to connect an ElastiCache Redis to an Express server deployed on ECS.

I get the Primary Endpoint from ElastiCache as blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com:6379

In my server I try to connect like this

const { createClient } = require("redis");
const pubClient = createClient({ url: 'blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com:6379' });

But when I check the ECS logs I see

/usr/src/app/node_modules/@redis/client/dist/lib/client/index.js:124
throw new TypeError('Invalid protocol');
^
TypeError: Invalid protocol
at Function.parseURL (/usr/src/app/node_modules/@redis/client/dist/lib/c...

Any help on what I might be missing
Thanks

this should fix it

const pubClient = createClient({ url: 'redis://blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com:6379' });

Thanks!

Now I'm getting a Redis error ConnectionTimeoutError.... exactly similar to #1656. after looking at the stack trace
but anyway this should mean I connected to Redis at least once?

Have you tried connecting using redis-cli?

[cmgchess]

i tried with that too
C:\WINDOWS\system32>redis-cli -h blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com -p 6379

and got
Could not connect to Redis at blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com:6379: Unknown error not connected>

even whitelisted my IP in inbound rules of security group
and then found this
i'll try some other things as well

However I managed to connect to it from an AWS EC2 using EC2 Instance Connect.

I guess this is how it behaves and I cannot access elasticache from a local machine without SSH. Anyway it works fine inside the cloud.
closing this
Thanks for helping me out!
