I have a running website (www.punditify.com) without any issues with my hosting company (fastcomet.com) and Cloudflare. However, I just created a new subdomain (blogx.punditify.com) under my existing domain. I added A record and IP address where this subdomain is hosted by another server. Both hosting companies have already created my subdomain at their side. For some reason, my subdomain cannot reach my second server. But, if I use the IP address of the main domain hosting company (fastcomet.com) my subdomain reaches my primary hosting company. With this subdomain, I use a specific web app where I needed to have my dedicated server from my secondary hosting company due to reason of session time-out issues with another server. Any help is appreciated.
