One Possible Quick Fix For A Non-Redirecting Subdomain Error

Quick fix for non redirecting sub domain

I was adding a new subdomain for redirecting for, following the instructions from a link shortener service – Rebrandly. So I added the records into the A type with the name go and the specified IP address.

Subdomain added on Cloudflare

However hours later, when I went to the, an error showed up stating somewhat an error on the host. I even added the go record at the domain name registrar and at the hosting company DNS editor but to no avail.

No, I do not think it is because I had not waited for the DNS propagation because the did not seem to reflect any changes at all. That error persisted even after I bought another new domain name later and the DNS records were propagated correctly. I highlighted the problem to Rebrandly and finally, one piece of helpful advice was given.

Indeed, when I set the SSL from Full to flexible on Cloudflare, the problem got solved, probably immediately or within an hour.

Cloudflare Flexible SSL

Depending on your level of comfort for site attacks, setting to flexible SSL may not be your preferred choice.

I probably have spent more time than I preferred on SSL-related issues, but it can be a common one considering most or nearly all sites will use SSL to secure their sites anyway.

Flexible SSL may solve your subdomain redirection problem. If you are not technically inclined at all, then some paid hosting or sites services may offer integrated or additional add-ons such as Cloudflare.
