Describe the problem

All of the sudden I was unable to access my self-hosted portal due to net::ERROR_CERT_DATE_INVALID when making GET requests to https://<hostname>.com:33073/api/users for example. After a review of the logs on the management container, I see a bunch of IPs are failing to connect which leads me to believe that all the netbird clients are unable to connect as well.

The cert for https://.com:443 is valid/not-expired, etc, but it appears the management API uses a different cert or something for some reason?

@clarkmcc commented on GitHub (Jan 16, 2026):

I re-pulled the latest docker images and rebooted the containers and that fixed it.

docker compose pull
docker compose up -d
