Why Materialize template redirect from localhost to 127.0.0.1 after login? - next.js

Question

I have added a custom login handler for Github:
const handleLoginGithub = (
params: LoginGithubParams,
errorCallback?: ErrCallbackType
) => {
axios
.get(authConfig.loginGithubEndpoint, { params })
.then(async (res) => {
/*window.localStorage.setItem(
authConfig.storageTokenKeyName,
res.data.accessToken
)*/
const returnUrl = router.query.returnUrl
setUser({ ...res.data })
await window.localStorage.setItem('userData', JSON.stringify(res.data))
//router.replace('/home')
})
.catch((err) => {
if (errorCallback) errorCallback(err)
})
}
There is no redirect from localhost to 127.0.0.1, but it will happen, do you know why?

The reason why I am asking is, that in dev environment cookie will not be stored if it happens.
