I’ve tried adding a sub-domain flip.etherace.io to my Cloudflare DNS sectin and point it to my origin servers but it always responds with 502 Bad Gateway. I’m somewhat certain Cloudflare is not the problem, I checked the post What should I do after seeing a 502 or 504 gateway error on my site? and it returns the first of the two pictures. I have opened a ticket and submitted a .har file.
The reason I am asking here is because I’m hoping someone could tell me what could be the possible problem, possibly with my Cloudflare set-up or my origin server. I asked my origin server provider and they said “We think that you still need to add this sub-domain to your DNS because it is not resolving at the moment.” How do you check if a domain is resolving? I’ve used different tools such as ‘nslookup’ (for Windows) and it verifies my record exists for the sub-domain is added correctly. Also I’ve already added my sub-domain to my Cloudflare ‘DNS’ section for four days now so I’m not sure what they mean by adding it to my DNS. I originally created my sub-domain in my cPanel account with my origin server providers.
Please let me know if I can supply any more information on this and thanks for any help!
