try to add a 3 second sleep before you start your app
Are you using an url string connection? I had to add
?family=6 at the end with ioredis to work with ipv6 addressthat is a very good point, ioredis assumes ipv4 by default for some reason, but this error comes from a node api and not ioredis, leading me to believe this error is being caused by the internal dns resolver not having started yet (takes ~2 seconds)
hey Brody sorry to ask here but since jeremy pointed the ?family=6 I remember you mentioned something similar that ioredis assumes ipv4 (was trying to connect Redis to n8n using private network), does that ?family=6 in the url could help with that?
do you remember what I'm talking about?
I do remember exactly what you are talking about, but to my memory n8n doesn't take a url for its redis connection?
edit: I was correct, they take the individual username / password / host / port type variables, so there's no way to pass in family=6

there is this thread, if they implemented what was suggested it would solve our problems

@jeremy family=6 works for me. thanks!
@Brody the timeout trick does not seem to work for my use case.
awsome!
