Always shows 500 error page on dev.gokhalemethod.com. This started when I put the site on maintenance mode, in this mode the site header response is 503 so it showed the error page which was expected.
I now after the maintenance tried to take the site online and now the site should be functional but it still continues to the error page. When I disable the proxied setting of the sub domain then the site starts working but with proxied it again shows the error page.
What I need to do to get this working again?
I asked the same on support ticket at Cloudflare Help Center but no one replied it.
