Recently I was under DDoS so the system may have banned your IP. Is the IP you are posting right now the one you are having issues with? I don't see it blocked in the ipconfigs nor cloudflair.
Actually if your IP is banned, you should see a cloudflair message about it.
If not, you are probably surfing really fast, at which just refresh.
Also, I had to limit to about 5connections per IP and up at about 2 or 5 requests per second do decrease the huge amount of people who scrape/DoS my site, causing it to stall. I can increase the limitations to 10req/s and 10conn per IP.
