In my country, an O and a 0 count as the same letter/digit on a licence plate. Same with B and 8. I think there's a few others. There are no two plates that only have the difference of these similar characters, the use of one counts as the other.
I'm finding it hard to explain, but I hope that makes sense.

You can get around this by extending your network with a VPN. I know that's an extra config, but a lot of people who are setting up home labs are already doing this anyway.
How does jellyfin offer remote streaming without a VPN?
