Access to musescore.com was denied

Hi Folks,
I know musescore.com is a separate site with its own support community. I've been developing a site with embedded musescore.com scores locally on my computer. After testing the embedded player, I can no longer access muesscore.com to get support! I get a blank screen with a "Access to musescore.com was denied" error. I've cleared my cache, tried different browsers, no change. I am not using a VPN. Perhaps their server thinks my private dyanmic IP is a spam bot? Anyway, I can't even access their support. Any suggestions? I never had that happen before where I've been blacklisted from a whole site? I'll try again in a couple of hours. I am unable to manually change my IP address. It's assigned by my internet provider, Shaw.

EDIT: I was to use a Proton's free vpn service to access the musescore.com to contact support directly. Hopefully, they can do something on their end.
