Mongo not able to start

Steps to reproduce

sudo snap install microk8s --classic --channel=1.26
sudo snap install juju --classic --channel=2.9/stable
microk8s.enable hostpath-storage
juju bootstrap microk8s
juju deploy ch:mongodb-k8s -m test --channel 5/edge --storage mongodb=50M

Expected behavior

Mongo is usable after deployment.

Actual behavior

Charm shows mongo as usable, but the following errors are seen in the log, and the pod does not respond to port 27017 externally.

root@mongodb-k8s-0:/# nc -zvw1 mongodb-k8s 27017
nc: connect to mongodb-k8s (10.152.183.20) port 27017 (tcp) timed out: Operation now in progress
root@mongodb-k8s-0:/# nc -zvw1 127.0.0.1 27017
Connection to 127.0.0.1 27017 port [tcp/*] succeeded!

Operating system: Ubuntu 22.04 Juju CLI: 2.9 Juju agent: 2.9.45 Charm revision: mongodb-k8s 5/edge 36 microk8s: v1.26.10 revision 6102

Additional context

This charm has been used in OSM for a long time, but unfortunately just recently stopped working in all releases (v10.0, v12.0, v14.0). The community is going to be replacing Mongo Charm with a Helm chart as they no longer trust charms.
