I really don’t. I’ll try and see more today. I did about 5 different setups thinking some port issue or ip being blocked by Twitter. Until I had removed everything and noticed that was only thing I hadn’t checked. Removed it and Twitter started working again on test server and then on main after I removed it. Added it back to test server to verify and Twitter stopped working on it again. Was already past 3am and needed to sleep.
Twitter login is important to me as well as using cloudflare. The majority of the market I’m pushing towards use Twitter. It didn’t matter if I had it turned on to route traffic thru cloudflare or had it off on cloudflare. As long as it was on the site site setup Twitter wasn’t getting thru. I left an active server up and will mess with more until it’s working.
