Unstable Cisco AnyConnect connection

[Susja]

Hello,
I am using business issued laptop running Monterey
I have two options to connect to business network: Citrix and Cisco AnyConnect. I prefer to use Cisco. It worked fine for a long while.
Two days ago I startled to experience the issues with Cisco.
It could connect to VPN server but fails to establish connection.
The weird thing is that it’s not consistent. I mean some days it works and some it doesn’t.
I contacted my ISP and they didn’t find any issues in my home network. I contacted my business IT and they said that nothing has changed on existing VPN server and they don’t have a problem to connect
What I could try to do from my side?
Thanks

Make sure iCloud Private Relay is disabled, “Turn off Private Relay for a specific network on your Mac”https://support.apple.com/102022

Try another DNS server

bogdanw - thanks for reply but we are not using iCloud

Even if you are not using iCloud, uncheck "Limit IP address tracking" from Network settings, Ethernet or Wi-Fi.

bogdanw:
I unchecked the option but it didn’t make a difference

Whatever I do … I’ve got this error:

I would like to try to re-install application. I don't have access to media, but I see in Applications folder the following:

Will it be safe to 'Uninstall application' and then reinstall it?

Thanks

AnyConnect is typically configured with multiple gateways to choose from. Try a different gateway server.

Thanks,
I already tried it … unfortunately without luck
Since I have another option to connect to network ( I could use Citrix ) I am inclined to monitor it for some while.
My gut feeling is that something has changed in environment (either my MacBook or company’s network)
My experience also points that sometimes new updates could fix it.
I am inclined to conservative approach

If Cisco AnyConnect is using IKEv2, see "IKEv2 VPN no longer rekeys so VPN connections drop every 20-25 minutes"
