CORS not working

[progonn]

Hi,

I am trying to get over the blocked by cors policy error when accessing hassio through a local website.
I added

http:
  cors_allowed_origins:
    - http://mysite.localdomain

to the configuration.yaml but that doesn’t change anything. Any hints on what I missed in order to get this working?

Thanks!

was able to get around this by sing nginx addon and this config:

How do you send CORS header with NGINX Proxy Manager?

Hi, in case you are still interested: domain: hassio.localdomain certfile: fullchain.pem keyfile: privkey.pem hsts: max-age=31536000; includeSubDomains cloudflare: false customize: active: true default: /nginx.conf servers: nginx_proxy/*.conf and then creating a file called “nginx.conf” in the /share dir with e.g. add_header Access-Control-Allow-Origin *; (example might expose security risks)
