When user login , it create cookies by login api . Right?

But when I add ssr data fetching with Firestore , some cache are still there I think. Then my localhost backend is broken . But after 5 days , everything is working like normal . It is Firebase cache problem?
There is no storage data in browser's localhost .
After I add SSR in indexjs , it happen.

I solved these by adding url in google cloud console.
But I still don't understand when I use ssr and this need , when I don't use ssr it doesn't need . I mean I don't use ssr I deleted but ssr is still aliving .
