new brand CNAME shows 403 when trying to access landing pages.

Hi,

 

we did setup a new CNAME for a new brand.

The CNAME looks like:

info.[brand].com.  IN CNAME [marketo-instance].mktoweb.com.

[marketo-instance].mktoweb.com. 300 IN CNAME sj11.mktossl.com.
sj11.mktossl.com. 300 IN A 104.17.72.206
sj11.mktossl.com. 300 IN A 104.17.71.206
sj11.mktossl.com. 300 IN A 104.17.73.206
sj11.mktossl.com. 300 IN A 104.17.70.206
sj11.mktossl.com. 300 IN A 104.17.74.206

 

In addition to that, we added the new domain as a domain alias to the Landing page rules.

But when we try to access the landing pages, we get a 403 result instead of the actual landing page.

Does anyone has an idea what the issue could be here?

Hi,

 

yes exactly. The first CNAME was info.biotronik.com. The second is info.mst.com.

 

Does the SSL/TLS Certificate have influence to it to have it working? And do you have a hint where to set this up/purchase?


@eyilmaz 

This is not an area I am an expert in.   Reach out to Marketo support and let them know you use and see if there is any additional configurations needed.

Cloudflare, Inc. for  -> info.biotronik.com

and

McAfee Inc.   for  ->  info.mst.com

 

When I try an access info.mst.com/Test2.html  I am blocked by a failing SSL inspection.

Hello @eyilmaz ,

Do you mind putting the actual CNAME and a Test Marketo Landing Page in here so I can check on it?

Thanks,

oz

Hi,

 

Here is a test landing page:

https://info.biotronik.com/Test2.html

and the new cname would be info.mst.com, So I would assume the same landing page accessible via info.mst.com/Test2.html

Ok.  Two different top level domains. Not that cookies would not be shared accross domains, but you may have already known that.

 

Assuming you first started off with info.biotronik is your first CNAME, you added this as your 2nd info.mst.com?

So in Domain alias you added this info.mst.com

 

Have you purchased SSL/TLS for both top level domains? If you purchased it for the first one you will need to do it for the 2nd one as well.
