i need a vpn expert

i need to find a vpn service that will allow me to connect to VMware Horizon Client. I tried with express vpn but for some reason it does not let me conmect. i use VMware Horizon Client to connect remotely to my cloud environment for my employer in the UK and i need the vpn when travelling and connecting to VMware Horizon Client from overseas. With express vpn activated, i am not able to connect to VMware Horizon Client at all, even when choosing different locations within UK. my first suspicion is that my employer might have applied a block within VMware Horizon Client for vpn? i need to find a way to connect and for this reason i need your help
