I’m trying to set up a reverse proxy for my Hubspot account. I followed the instructions to find the proxy\_pass destination and it comes out to be \<my-hub-id\>.sites-proxy.hscoscdn02-na2.net since my account is hosted in the US-West region. This CNAME however does not resolve. I used this document to arrive at the proxy destination: [Accounts Dashboard | HubSpot](https://developers.hubspot.com/docs/guides/cms/content/performance/reverse-proxy-support#1.-configure-the-proxy)

In fact, I don’t get an NS record on the domain the domain [sites-proxy.hscoscdn00-na2.net](http://sites-proxy.hscoscdn00-na2.net). I get an NS record when I try [sites-proxy.hscoscdn00.net](http://sites-proxy.hscoscdn00.net). I also get an answer when I try to resolve \<my-hub-id\>.sites-proxy.hscoscdn00.net.

I tried creating a reverse proxy setup using the US East region address and I get a 421 Misdirected response when I proxy to this destination. I cannot use the US West address which is the correct one since it doesn’t resolve.

Is there a mistake in how I have created the proxy URL for my account? Am I referring to documentation that is outdated?

After probing around a bit, I found that name servers are configured without the HubID suffix for regions outsude US East. So [hscoscdn00-na2.net](http://hscoscdn00-na2.net) does not resolve but [hscoscdn-na2.net](http://hscoscdn-na2.net) does. Without the zone suffix, the numeric suffix is required as shown in the documentation. I tried setting up the proxy with the na2 suffix, without the numeric suffix, but I still get a 421 Misdirected Request response.

You need a HubSpot enterprise account to setup a reverse proxy.
