My website is setup with Godaddy server with Cloudflare. It’s working fine last 6 month. I am getting error “HTTP ERROR 500” today. I contacted to Godaddy support and they said you have to check with Cloudflare because we have used Cloudflare nameserver.
A 500 comes from your server, so I am afraid you will have to go back to your host. Hosts typically use the nameserver argument as a way to wave off such issues.
