Sophos Connect Client fail because IKE UDP Port seems to be blocked

Hello,

Yesterday I have done a firmware upgrade on my XG to 17.5 MR10 and after that update I can no longer connect to VPN using Sophos Connect Client, I get a message saying the IKE UDP Port seems to be blocked, I have already tried to route my internet through my 4G and faced the same issue.

Thanks
