[BUG] Coder v2.19.1 on EKS - port-forwarding UI button disappears after some time

Hi all - currently running Coder v2.19.1 on EKS with wildcard subdomain proxying. Works like a charm. However, I notice after a while, the "Open ports" button on my Coder agent's UI disappears. It comes back right away after I restart my Coder server's pod. The same applies to Coder apps that use subdomains. Additionally, having saved the URL of one of my subdomain-routed apps, the actual app remains accessible even though the "open ports" button disappeared and that app's button became unclickable. Accessing the URL made those buttons alive again the same way restarting my Coder Server pod did. For context, workspaces run on EC2 instances that are started/stopped - so not ephemeral. The coder_agent resource is persisted accross restart, i.e. I am not using the 'count' parameter. If curious why, this prevents me from modifying the EC2's 'user_data' cloud-init script, which otherwise makes start/stop operations very slow. Has anyone run into this issue?
