Proplem when point domain and subdomains to different hosting IP

Website, Application, Performance DNS & Network

Hi,

I use cloudflare with my main domain name at groupbuyexpert dot com
I point the main domain to hosting IP A (example)
then I pointed the sub domain , adplexity.groupbuyexpert dot com to hosting IP B (this is linux vps)
now, when I visit adplexity.groupbuyexpert dot com, it says error with my hosting. But in my hosting, I already added adplexity.groupbuyexpert folder

I pointed another sub domain : tool.groupbuyexpert dot com to hosting IP C (this is windows VPS), and when I visit this subdomain, it says not found,
so how should I fix?

thanks!

Now, i fixed the hosting IP C (as mentioned), it is windows VPS
but I have another proplem. If I turn on SSL (Always Use HTTPS), then i cannot visit tool.groupbuyexpert dot com.
but if I turn off ssl, i can visit tool.groupbuyexpert dot com without any proplem
is there any error ?

What error do you get when you try to visit the tool subdomain with SSL turned on?

when i try to visit tool subdomain with ssl turned on, the website is not loading

it says error

Connection timed out

It sounds like your server isn’t responding to HTTPS connections for that hostname.

oh, it mean that I need to install ssl to that hostname ?

Absolutely. Every site should have SSL before adding it to Cloudflare.
