i talked to bluehost support and they can't help with cloudflare. They suggested to point my website back to bluehost instead of cloudflare. I contacted cloudflare and haven't gotten any response yet. I read about a http keep alive connection but not sure if that would help.
Error 524 indicates that Cloudflare successfully connected to the origin web server, but the origin did not provide an HTTP response before the default 100 second connection timed out. So how would my page send an HTTP response while the send mail is running?
