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.astervariedades.com.br; astervariedades.com.br only redirects to it
How we decided: astervariedades.com.br forwards its homepage to www.astervariedades.com.br; your homepage names www.astervariedades.com.br as its canonical address; and your UCP profile is served directly at www.astervariedades.com.br/.well-known/ucp. An agent given astervariedades.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 astervariedades.com.br too if agents may use it.
