Would you mind sharing more about the issue? We have enterprises running NetBird with thousands of users with near zero issues. Apparently it is usually other way around - people migrating from Twingate to NetBird because of the former solution instability. Well, that is from our experience.
I suggest trying NetBird cloud to eliminate a potential misconfiguration of the self-hosted instance.
DNS resolution failures occurred inconsistently—sometimes due to browser caching when accessing web resources, but often for no apparent reason. For some users, restarting or reconnecting Netbird resolved it; for others, it didn't. The fact it worked flawlessly for some users while barely functioning for others suggests client-side issues. We also saw sporadic failures in cron jobs (like DB exporters) that never happened with Twingate. We followed the Helm chart configuration exactly and properly configured the Network Load Balancer with appropriate timeout settings.
