Azure VPN client unreliable on Linux

I'm writing this with sadness, but I've wasted a couple of days trying to get the Official Linux Azure VPN client working reliably, and ended up with a Windows 10 VM that works fine. My situation; I'm working over Starlink, so internet via CGNAT. Works perfectly fine, and I've worked with Google cloud vpn for more than a year over Starlink. I needed to connect to a vpn on Azure, so installed the official Microsoft VPN Client. This is only supported on Ubuntu 22 and 24, so I set up a VM with Ubuntu in the linux host. Result, random TLS disconnects, more than 80% of all tls transactions. Impossible to work with! My colleagues on Macs said the same product worked fine on Macs, but I don't have one here. My thinking was that it might be the CGNAT, which causes your ip address to change quite often, so I enabled a VPN on my Linux host to freeze the host IP. No change in the VM, still unreliable. So I set up a host on Google Cloud, with a full UI because of the graphical nature of the VPN client. This host has a fixed public ip. Still unreliable tls! I finally ended up setting up a Windows 10 vm on my Linux+Starlink host, and installed the VPN Client on that VM. Finally reliable VPN. Conclusion, the Linux Azure VPN Client does not work reliably. You can have random drops in TLS connections. I'm probably running into the same bug as [these Cisco engineers](community.cisco.com/.../2), so hardware issues in Azure servers. I presume the Windows and Mac clients work around these.
