Stuck on #NA2: no content received

Hi. I can’t figure out what’s going wrong here.

Locally, I can start the server, start 3 replicas, start a redis-cli and issue WAIT 1 500 and everything works.

But remotely, I get “no content received.”

Can you help me figure out why please?

The code is a simple for loop and it works locally…

@devfire I’ll take a look at your code as soon as possible, though I may need a few days to get back to you, as I’m a bit tied up at the moment.

I think I found an incorrect sleep implementation that was causing the entire process to hang. Let me fix that and if I still have an issue, I’ll report back. Thanks.
