Not able to access any HTTPS URLS


Istio 1.1.4
When I try curl from pods with Istio-proxy side car
I get error:
curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
We have this issue only on one cluster. Another cluster with same version of Istio has no issues.
Any help on debugging this would be a great help.
