atcangbian I bind my domain: https://aigchub.top to CloudFlare, and the A record points to the Serv00 IP. I've been accessing normally before, but from today https://aigchub.top returns 'Bad gateway 502'. And I can access my site directly through :http://128.204.218.48:3008/, what's the problem with this.
admin atcangbian check your application's logs, including the access log, and report the issue to Cloudflare.
