Hi,
We believe the issue came up from a recent change we did in the network policies. We have restricted some traffic and is affecting the communication between services exposed in Okteto when using the public endpoint. To communicate with services within the same namespace, we recommend you to use the service name instead of using the public domain, the request will use the internal network and have better performance.
We are working on changing these rules to allow again that traffic. I’ll let you know when we apply the changes.
