Hello there,
I’m trying to share one loadbalancer (client-service) between two deployments(client-api and client-web). After apply the configuration, the two services works perfectly. However, after some minutes, the loadbalancer stop working, causing the service unavailabilty.
In order to restart the loadbalancer, I have to press F5 for while and the service start working.
Could someone help me?f you guys need more information, please, let me know.

The proper way to share an LB between two services is to use an ingress controller along with ingress objects to specify routing rules.
You can find an example in our community tutorials for how to accomplish this (you may not need to cert-manager part):
