DSN Error - Deprecated record

Hey!
I'm hoping someone can help me, in Squarespace it says there that there is a DSN error, and that the CNAME has deprecated. From reading online it sounds like 'deprecated' records happen when they've been outdated, but I don't know how to go about updating the records? 

Please see screenshots that show what I see in Squarespace and Freeparking (who the domain is through).

Thanks so much in advance!

I would suggest that you delete the www - ext.squarespace.com record in freeparking and then replace it, that may be enough to fix this error. If not then talk to freeparking support to see why the record may have been depreciated.

Thanks so much for the help! I've changed the CNAME to ext-cust.squarespace.com so hopefully that fixes it!

I'm a bit confused because when I use SQ connected my GoDaddy DNS setting, the Second CNAME was pointed to "ext-sq.squarespace.com." (there's a "." in the end"), it connected well, and works!

Later, I found the the guidance on SQ website, says the second CNAME should point to  "ext-cust.squarespace.com" (there's no "." in the end, and the starting value is different as well)

My website is running fine and still points to "ext-sq.squarespace.com.", should I change to "ext-cust."?

I checked my older SQ site, it is also "ext-sq.squarespace.com."

I am confused.

Thanks

Just confirming that changing the CNAME to ext-cust.squarespace.com through the domain provider fixed the issue! It did take about 48 hours to take effect. Thanks again for the help!

They use ext-sq.squarespace.com to indicate a subdomain (when the main domain points to another Squarespace site) but you do not need to make any changes unless errors are shown in the Domains panel.
