I didn’t go through all the countries, so there’s likely some more that work, but Costa Rica, Estonia, Georgia and North Macedonia all look to have servers that aren’t blocked at the moment.
Try disabling VPN and any adblock extensions (or try a different browser that doesn't have any built-in adblocking). If that doesn't work, there isn't any more you can do. If I recall, there was a certain time/date range where they had a server issue that led to the loss of many videos.
