According to ExpressVPN support they don’t support any more USA streaming using a router and OpenVPN protocol so why they keep advertising it !
I can use Hulu with their application but not when I connect to my router with open VPN connection to various servers
This is not what I expected when I got their service !
Same for me two weeks ago - manual config openvpn client stopped working for UK streamed services. Told they had stopped supporting, now with NordVPN 
Got an account with Surfshark !
I recommend you to switch VPN providers. Or to get their Aircove Router.
Thanks
Any recommendations for a good VPN streaming provider for USA streaming?
I thought express vpn is in vpn service providing and not hardware sale
I have a gl-mt3000 router that supports verious vpn protocols
ExpressVPN was initially offered for 3rd-Party routers. I installed it on a Linksys WRT3200ACM with great success. They announced the Adblock feature and I was very interested in that. They walked back on that and I decided to buy the Aircove. Not as powerful as Linksys hardware, and the firmware still needs to offer some missing features. The big advantage is ANY device (Refrigerators, Smart TVs, or your Chinese Light Bulbs) can use ExpressVPN! For Laptops and SmartPhones, it’s then optional to run it on the OS (at Starbucks or Work when you need it.)
My Pixel 7 Pro runs ExpressVPN nicely. If you are connected to a trusted internet connection (your Aircove Router) It can turn off the ExpressVPN app/program automatically. Let your Aircove do the work.
