Virgin media wired connection not working - wireless is fine

Connected Virgin media Hub 5 to my Xbox series x via a Cat6 ethernet cable. Xbox says I'm connected to the Internet but I'm not able to sign in and I'm getting error code 0x87dd0017. None of the troubleshooting suggestions associates with that code have worked.
Wireless connection works fine - just want to use the wired connection for better speeds. Any suggestions?
