No, I had to take a nap. I'm back up now and will be for a few hours if you still need help. You can start a chat with me here - or at least I assume you can.

I'm assuming you are on a VPS?
I've only installed one site using NodeBB, but it did not seem that hard. I'm about to head off to a nap (been up for 28 hours) or I'd volunteer to help you immediately.
If you can't find anyone in the next 10-12 hours hit me up and I can probably help out as long as it is just a simple install of NodeBB and using nginx as the proxy. If you have CloudFlare in front of it that you will have to take care of yourself most likely, but there is not that much to it.

Just to mention, I think Amazon SES blocks sending on port 25 by default. They advise you to use 587 and StartTLS instead. If you have to use port 25 you are required to submit a request for them to allow it for you.
I ran into that on helping a Xenforo admin that was wanting to use SES and was insistent that port 25 was what they wanted to use for some unknown reason.

@darkpollo said in NodeBB and Cloudflare:

Is this still an issue? I cannot find any more info in the docs and I would like to use CF with Nodebb...

We are using NodeBB on a alternative Xenforo support site.
We are also using it behind CloudFlare successfully. I had numerous issues before I realized I websockets were in use and remembered it was an option in CloudFlare.
Currently their free plan does allow the use of WebSockets, but you have to turn it on as it is off by default.

It is located under your Network tab in the CF control panel.
