Cannot connect to company Cisco AnyConnect vpn

[kasakaa]

Since Tuesday 3rd September 2024 I am unable to connect to my company Cisco AnyConnect VPN.

I was able to previously, last successful connection on Monday 2nd September 2024. I can connect to the VPN on other connections such as office WiFi and mobile hotspot. Company IT have confirmed there have been no changes on their end. I am able to connect other devices to home TalkTalk WiFi. I have tried wireless and wired connections to TalkTalk hub without success.

I can see there have been similar cases in recent weeks (https://community.talktalk.co.uk/t5/Broadband/VPN-connection-issue/m-p/3063029, https://community.talktalk.co.uk/t5/Fibre/Connecting-to-company-VPN/m-p/3062701)

WiFi Hub Router firmware is SG4K100202 

I have updated my community profile with everything except my landline number, which I cannot access as I am currently getting an error when I try to log into my main TalkTalk account.

If a new router is a potential solution, I would be happy to receive one.

   • Cisco AnyConnect tries all available VPN connections, then gives an error message saying "Unable to connect". I am unable to take screenshots due to company IT policy.

I have tested all of the free VPNs that I could with V202 & V174 before then and they all worked fine. What VPN protocol is this Cisco VPN client using? What is the router's firewall level set to, it should be on medium?
