Windows VPN not connection. Error 809

Hi, I use multiple Windows VPN connections and DrayTek VPN connections to connect to my clients and last week all the windows vpn connections stopped working. I have tried everything I can find on the web to resolve and I want to rule out/determine whether its Sophos that is blocking the connections. I'm getting error code 809 which, on research suggests that ports UDP 500 or 4500 might be being blocked. I find Sophos quite complicated to work with and would appreciate any help on diagnosing or resolving this issue. I have the following products on Windows 10

Core Agent 2022.4.3.1

Sophos Intercept X 2023.1.1.6

Device Encryption 2022.3.0.21
