I have a small k3s cluster on Linode with a node app that talks to a GCP hosted MySQL instance. Fairly frequently, I have issues where the app can't talk to the MySQL instance on boot, but the pod will be fine after a restart. Connections are performed via IP address, so its not a DNS issue afaik. Are there any ways I can debug this and maybe pinpoint this to being an app or hosting provider issue vs something in k3s? This app was working just fine under heroku.
