Kalu AUR Error Message

I am getting the following error message on Kalu when checking for upgrades.
Unable to check for AUR packages
Invalid JSON response from the AUR

I was just wondering if anyone else has noticed this and or has an explanation. I had installed ufw and set basic firewall rules and thought maybe that was causing it. I have tried disabling it and it seems to still be giving the same response.

Seems like it’s now working without any error messages.

yeah aur/archlinux.org was in maintanance
