For some reason every few minutes Cisco anyconnect VPN client keeps disconnecting and reconnecting.

Example log:

For me what solved this is to work only on wifi or only on wired ethernet connection (I disabled the wifi adapter (in Control Panel\All Control Panel Items\Network Connections in win10)

Now everything is stable!

I had the same issue and inspired by thedrs answer, I disabled all network adapters I didn't need for the VPN connection.

It turned out that the Hyper-V machine (and the corresponding virtual Ethernet adapter) I had running were causing it. After shutting down the virtual machine, no more reconnects occurred.

I know this thread is old but I just ran into this problem (it would reconnect at least several times/hour - sometimes several times within a 60 second span). The above two solutions didn't work for me (disabling unused network connections, shutting down hyper-v machine) but what DID work for me was disabling IPV-6 under network connections:

Open up network connections, right click on wi-fi or ethernet, go to properties and uncheck the box corresponding to Internet Protocol Version 6.

I thought I saw that suggestion in this thread, but I can't find it anymore. Good luck!

There are 3 parties involved in this problem. Cisco, your IT dept, and ISP. They can fix it by either changing group policy and moving the port, etc. Apparently, your ISP is limiting and disconnecting people using VPN to watch overseas TV. That's why your company VPN keeps reconnecting. But when you call them, they will point to the other two parties. So the ONLY and easiest way for you to do YOURSELF is to disable all other connections, including Bluetooth, Virtual Machine, Wired (if you're on wireless). And for the remaining wireless AND AnyConnect connection, UNCHECK IP6 from the network properties! Easy fix by yourself and work and uptime 100% for those WFH and Covid Lockdown folks.
