Unstable connection with workstations

We migrated our workstations to a new server (version 2024.08.07.0819). Yesterday, we noticed that the connection was unstable (the workstations would switch from online to offline several times within a minute). deployed the server on Ubuntu 24.04 in docker and configured nginx for port forwarding from port 5000 to port 80. For installing remotely agent was used (PowerShell -ExecutionPolicy Bypass -Command "Invoke-Expression ((New-Object Net.WebClient).DownloadString('http://remotely.ca.company.com/api/ClientDownloads/WindowsInstaller/63347029-c223-48fc-af21-71695ba430bd'))"). The firewall on Ubuntu was disabled, and all traffic was temporarily allowed through the firewall.

Has anyone encountered this problem?

Start with the server deployment on Ubuntu 24.04 in Docker, nginx port forwarding from port 5000 to 80, and the Windows remote-agent installation command. Reproduce the repeated online/offline transitions and inspect connection behavior across those components. Done means identifying the cause and restoring a stable workstation connection.
