Does this work when both nodes are behind CloudFlare's reverse proxy?
When I tried to connect my first site with MainWP I got an immediate 523 error.
All my sites are behind CloudFlare's reverse proxy, including the main node, and so when I looked up CloudFlare on their site I found a workaround which said, basically, disable CloudFlare's protection.
Now, call me old-fashioned if you like, but that doesn't rate as much of a workaround in my book. Not even a kludge!
I have years of experience with multiple servers working with CloudFlare, so its a 'big ask' to get me to switch off their security, which has saved several sites of mine on more than one occasion, and trust MainWP's which, as far as I am concerned, is a big unknown quantity.
So, how about a REAL solution from iControlWP? One like ~ if you just whitelist these IPs and do this or that, everything works fine and the error 523 goes away?
But not switch off Cloudflare's security. That's a non-starter, at least for me it is.
