I know this thread is months old, but I'm having this issue again -- pretty badly now!
My forum goes down more and more often ("429 Too Many Requests") because there are THOUSANDS of "users" on the "logging in" page at the same time. BOTs, no doubt. Is there any way (via the UBB control panel or cPanel) to help stop this? Does this seem deliberate?
I tried enabling Cloudflare the other day and it locked me out of my own site! lol Even when I added my IP address to the Allow list, I couldn't even view the forum -- it said I didn't have permission! Another user reportedly said that it told him the "site doesn't exist anymore"! This is on PC/Chrome for me -- I was able to view the forums on my iPhone just fine. So I'm confused.... any ideas?
