Raspberry Pi seaf-cli

Maybe a stupid question. But in the past i had seaf-cli running on my raspberry pi. Today i was checking for updates and found out that deb.seadrive.org was not reachable. Looking for a solution i couldn’t find any reference to the raspberry pi anymore. In the install instructions they are mentioning Debian buster but that doesn’t solve the problem of not starting seaf-cli.

What happend whit it? is support dropped?
