Delegation list empty when. using VPN

Just want to report that if you come across an empty delegation list with a “No results found” message then check it isn’t because you are on a VPN. This was the cause for me. Looking at the Chrome developer info I see a request to https://a.adapools.org/yoroi-api/ fails with a 503 error when I’m on the VPN. Which is strange because if I open that URL in my browser with VPN still open it looks fine - I get a nice screen full of JSON. That’s probably because the Chrome extension is doing a POST and browser does a GET. If I replay the failed request via curl I see a response with HTML page saying it is checking the browser. But the response code is 503 which stops Yori displaying anything.
