[Ingress] curl: connection refused

Hello,
After applying the linkerd injection (Lab 11.2, item 11), curl gets a "connection refused" on the service Ip, but not on the pod Ip:
usercp@cpnode:~/ingress-nginx$ kubectl get svc | grep ingress myingress-ingress-nginx-controller LoadBalancer 10.108.235.235 <pending> 80:31860/TCP,443:32260/TCP 39m myingress-ingress-nginx-controller-admission ClusterIP 10.105.96.191 <none> 443/TCP 39m usercp@cpnode:~/ingress-nginx$ curl -H "Host: www.external.com" http://10.108.235.235 curl: (7) Failed to connect to 10.108.235.235 port 80: Connection refused usercp@cpnode:~/ingress-nginx$ k get po -o wide | grep ingress myingress-ingress-nginx-controller-qmdt6 1/2 Running 7 (52s ago) 9m33s 192.168.0.112 wnode <none> <none> usercp@cpnode:~/ingress-nginx$ curl -H "Host: www.external.com" http://192.168.0.74 <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> ...
and regularly, the pod is in CrashLoopBackOff state:
usercp@cpnode:~/ingress-nginx$ k get po -o wide | grep ingress myingress-ingress-nginx-controller-qmdt6 1/2 CrashLoopBackOff 7 (2m12s ago) 11m 192.168.0.112 wnode <none> <none>
It seems it happened too on the nginx-one deployment in Lab 11.1, but after deleting and restarting the deployment it went well

@thomas.bucaioni Had a similar issue with linkerd 2.11.2. You can check it with
linkerd version
.How to fix
kubectl get ds -o yaml | linkerd uninject - | kubectl apply -f - kubectl get ds myingress-ingress-nginx-controller -o yaml | linkerd inject --ingress --skip-inbound-ports 443 --skip-outbound-ports 443 - | kubectl apply -f -
Looks like a bug, but it works with this workaround suggested by @chrispokorni in https://forum.linuxfoundation.org/discussion/861348/exercise-11-2-ingress-controller-getting-error-503-service-temporarily-unavailable#latest
