Blue Iris

I have my router setup with Wireguard VPN so I can access my local network even if I am not at home.
The strange thing is that I can't use the widgets from the Android app if I am not connected to a wifi.( doesn't need to be my own wifi, any wifi with a internet connection works)
I can use the app itself to connect to Blue Iris without any problem, but when I am on mobile data the widgets doesn't load.

Anyone have a idea what's wrong?

Iam i the only one with this problem?

Does Wireguard VPN work with other programs on mobile data ? I'm wondering if this is a port blocked by your mobile data carrier.

Both the Blue iris app and all other apps i have tried works with Wireguard VPN, both Wifi and on mobile data.
And because of the VPN i should not matter what ports my mobile data carrier blocks, as long as they let the VPN tunnel through.
