Need guidance on cname

Hi,

My clients site is brainware.pk, i`m trying to point lms.brainware.pk to brainware.vedamo.com and t.branware.pk to another site x.theirdomain.com , i have “strict” as cloudflares ssl policy but both domains are going to random urls and not the correct sites, what am i doing wrong? i have used cnames.

The Origin server needs to accept the public facing Host header value, so you need to configure the origin servers to respond to the Host lms.brainware.pk or x.theirdomain.com.

If using Strict, you need to configure the origin servers with valid SSL certificates.

If you have an Enterprise plan you can use Host Header Override to avoid the first requirement.

Thanks, so i need to make a subdomain on my end or what do i ask the other company, what changes do they or i need to make?
