Angular interceptor stopping all http requests

I have an interceptor that is supposed to refresh an access token if it's expired and continue the request with the new token, but its just looping a lot (not infinitely, something is stopping it after 100+ loops) and I can't seem to figure out why, this doesn't happen when token is not expired.

let auth = inject(AuthService);
if (!auth.AccessExpired()) return next(req);
return auth.refresh().pipe(
catchError(() => next(req)),
switchMap((res) => {
var response = res as RefreshResponse;
const newReq = req.clone({
headers: req.headers.set("Authorization", `Bearer ${response.access_token}`)
})
return next(newReq);
})
)


This is the refresh function:

refresh() {
return this.http.post<RefreshResponse>(this.baseUrl + "refresh", {}, {
headers: new HttpHeaders().set("refresh_token", this.refreshToken ?? "")
}).pipe(
tap(
res => {
console.log('responded' + res);
this.accessToken = res.access_token
}
),
retry(2),
catchError((err) => {
console.log("errored", + err)
this.logout();
this.noti.showError("Your session expired, log in again.", 5000);
return throwError(() => new Error(err));
})
)
}
