Hi, we have been using Cloudflare for two websites for more than a month and it is working well to stop a DDOS attack.
However, sometime in the past week, when trying to view one of the websites from a specific Australian ISP, we are getting a 522 Error. We have troubleshooted, web hosting added Cloudflre IP addresses to whitelist, but still the 522 error shows up. Strangely, another website hosted at the same hosting company and within Cloudflare can be seen without issues. It is a multihost Magento site.
From all other computers and ISPs at different location, both the websites can be viewed successfully.
I try to enter the two traceroutes hre, but there is a restriction in this forum on first time users.
