Hi @Gouravdev

Taking a peek at past forum issues, it looks like this might be a TCP error. Can you check out this post and see if it might help you out here?

Error: write EPIPE

@DonHolmen This error means that the TCP connection between the n8n instance and the postgres database is broken. Since you are seeing the error regularly, that’d imply that there are regular network issues that are causing the TCP connection to be dropped. Are you using Cloud SQL for hosting postgres? or is the DB running elsewhere?

Hi @EmeraldHerald,

It appears that Redis is unable to connect to the n8n instance. To resolve this, do we need to enable queue mode on the n8n instance side?

Thanks in advance!!

Hey @Gouravdev,

What are you doing when you see that error? Normally n8n would connect to Redis but you can use Redis without n8n being in queue mode it just means n8n shouldn’t try and connect to it.

If you can share more information we can take a look, You do seem to be having a lot of issues with setting up queue mode if you want we can put you in touch with one of our experts who may be able to help you get up and running.
