Why can't I set cookies on localhost

Thanks for the reply,

Looked at some of those but not really my case.

In localhost:80 I'm using OctoberCMS (Laravel), and I don't even control the way it sets cookies, but am able to see it can't set any.

In Localhost:8080 I'm using Vue3, and VueCookieNext, and an example for a cookie set is:

VueCookieNext.setCookie('token', data.token)

Both are docker containers, but neither can set cookies in Safari, only in Chrome.

Still the same outcome with a valid hostname.

Kinda strange that it's only on Safari that this happens, that's why I came here and not OctoberCMS and Vue3 support.

Any other ideas?

Thank you in advance.
