Problem

The profile isn't served with the caching the spec requires

Served with Cache-Control "max-age=14400". Spec level: MUST.

To fix

The profile has no ETag or Last-Modified header

Spec level: SHOULD.

To fix

Your store lives on www.assistenciacuritiba.com.br; assistenciacuritiba.com.br only redirects to it

How we decided: assistenciacuritiba.com.br forwards its homepage to www.assistenciacuritiba.com.br; your homepage names www.assistenciacuritiba.com.br as its canonical address; and your UCP profile is served directly at www.assistenciacuritiba.com.br/.well-known/ucp. An agent given assistenciacuritiba.com.br instead gets a redirect, and the spec tells agents not to follow one, so it stops there. Serve /.well-known/ucp directly on assistenciacuritiba.com.br too if agents may use it.
