We have a public salesforce site (http://blah.force.com/example), but would like to set up a custom domain for this site such as: example.domain.ca
Using this Salesforce help article as a guide: https://help.salesforce.com/articleView?id=000205653&type=1 our DNS manager created a sub-domain example.domain.ca and pointed it to example.domain.ca.00ri00000000g5o.live.siteforce.com. This step was completed over 72 hours ago)
Now I'm trying to add the custom domain information to Salesforce (Setup > Domains > Add a Domain)
In the Domain Name field I entered the sub-domain created (example.domain.ca) and then selected "A non-Salesforce host or service serves this domain over HTTPS" with the value example.domain.ca
Unfortunately that results in the following error. 'Error: Salesforce.com can't validate the domain. The CNAME record may still be processing (which can take up to 24 hours), or the domain may not belong to you. Make sure the domain name example.domain.ca uses example.domain.ca.00ri00000000g5o.live.siteforce.com as its CNAME target and try again later. It presently uses www.example.domain.ca.00ri00000000g5o.live.siteforce.com as the CNAME target, which does not equal the expected value.'
I'd appreciate any help or ideas on what the issue could be.
