K8s config with correct token yeilds "Register tunnel error from server side error="Unauthorized""

Config: 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: tunnel
  labels:
    app: tunnel
spec:
  replicas: 1
  selector:
    matchLabels:

      labels:
        app: tunnel
    spec:
      containers:
        - name: tunnel
          image: cloudflare/cloudflared:latest
          args:
            - tunnel
            - --no-autoupdate
            - run
            - --protocol=http2
          env:
            - name: TUNNEL_TOKEN
              valueFrom:
                configMapKeyRef:
                  name: env
                  key: CLOUDFLARE_TUNNEL_TOKEN
      restartPolicy: Always

            - --no-autoupdate
            - run
            - --protocol=http2
          env:
            - name: TUNNEL_TOKEN
              valueFrom:
                configMapKeyRef:
                  name: env
                  key: CLOUDFLARE_TUNNEL_TOKEN
      restartPolicy: Always
Adding the protocol being http2 was necessary to get this working, also, I checked the token multiple times, its correct, here is the exact error: 
2025-03-26T18:36:51Z ERR Register tunnel error from server side error="Unauthorized: Failed to get tunnel" connIndex=0 event=0 ip=198.41.192.77
2025-03-26T18:36:51Z INF Retrying connection in up to 1m4s connIndex=0 event=0 ip=198.41.192.77
2025-03-26T18:36:51Z ERR Register tunnel error from server side error="Unauthorized: Failed to get tunnel" connIndex=0 event=0 ip=198.41.192.77
2025-03-26T18:36:51Z INF Retrying connection in up to 1m4s connIndex=0 event=0 ip=198.41.192.77
So cloudflare was working fine, until i started to get this issue. Since its not a incorrect token, what could it be? and how to fix, maybe its something that can be fixed in the k8s config
