Are you using an old version? No
Have you checked the changelog to see if your issue has been fixed in a later version? Yes no mention at all

That's not a valid hostname "some-redis.lrylbt.ng.0017.ap1.cache.amazonaws.com".

"0017" is invalid, hostname parts must start with a letter, e.g. "a0017".

AFAIK.

[iamcaleberic]

@mperham I hashed it a bit because I was sharing it in public anyway heres the URL:
****-redis.lrylbf.ng.0001.apse1.cache.amazonaws.com:6379

[mperham]

Same issue. 0001 is not legal afaik.

[mperham]

Either way, this issue is between your initializer and Ruby's URI parser. Nothing to do with Sidekiq afaict.

[iamcaleberic]

Alright thanks

[jeanpauldejong]

So what was the solution to this? I'm encountering a similar problem.

[mikegee]

@jeanpauldejong do you have new evidence that there might be a bug in Sidekiq? I think posting your specific details as a question on StackOverflow would be more effective at getting support.

[mperham]

@jeanpauldejong You'll need to give us the exact URI and error backtrace.

[ghost]

Sorry I resolved it :) And logged in under the wrong account, it is I @jeanpauldejong

Basically for AWS EB the REDIS_URL need to contain what makes an URI a URL...So the notation to use is:

redis://adfafdsda.cache.amazonaws.com:6379

I was missing the redis part at the front, I hope that helps someone else.
@mikegee @mperham thanks for prompting me to get back :)
