My site uses Cloudflare and keeps going down every day at about 11 PM with a 523 error for about 5 minutes. Afterwards, it is back up without any interference. I contacted the hosting company and was told that it was a problem with the Cloudflare connection. They cancelled my cloudflare and replaced it with a new one, but it didn’t fix the problem. Its very strange. Wondering what I can do to fix this or diagnose it?
