Rewrite to ALB in Amplify Redirects doesn't work?

App Id dqbbd1fflds4t

Region us-east-1

**Amplify Hosting feature: **Redirects

Hitting https://localizalia.dqbbd1fflds4t.amplifyapp.com/api/session from Portugal or Spain doesn't work. From Brazil it works.

rewrite entry not working:

{ "source": "/api/<*>", "target": "https://xxxxx-my-alb/api/<*>", "status": "200", "condition": null }

I suspect this has to do with tls1.3 because I see it in access logs and it is not supported by ALB.
