Cloudflare is stripping Cookies header from multi-level subdomain requests

You can test with the following URL by simply adding cookies in the devtools.

I’m returning the complete request context, headers.cookies is completely missing. On the top TLD I have no issues.

I tried development mode, cache bypass rules, everything I could think of.

If you are still facing this you could try to reduce the subdomain levels (making it first or second level) and test it again.

I can’t, I’m using Appwrite, it’s how cloud functions work in it.
