According to a thread by @LeGaulois, Ghostmixer.cc domain was discovered to have gone offline this year around March. Which means they had stopped operating
Unfortunately, i was unable to check the domain history of the mixer service in it's earlier days. All the data has been replaced with new domain info.
There is also no web archive of how the mixer looked like before march 2019.
