There a few things you can check to try and diagnose and resolve this.
Retrieve the logs for the container instance to identify any errors or issues. You can use the Azure CLI command:
az container logs --resource-group <resource-group-name> --name <container-name>
Restart the Container: Sometimes, simply stopping and starting the container instance can resolve the issue. You can do this via the Azure Portal or using the Azure CLI:
az container stop --resource-group <resource-group-name> --name <container-name>
az container start --resource-group <resource-group-name> --name <container-name>
Network Configuration: When container groups are deployed in virtual networks, port 19390 is required to connect to Container Instances from the Azure portal.
