Not sure where to put this issue. On https://skills.emsidata.com/ the functionality for searching skills seems to be blocked by virgin. If I tether my laptop via a mobile internet connection, the search functions fine. To test it, you scroll down the page to 'Skills library' and type something, e.g. Photoshop and the skill should pop up.
To make things more confusing, my friends have virgin broadband accounts and things are working fine for them.
I've switched off the virgin firewall and also tried returning my router to factory defaults.
Any ideas welcome.
