unknown command received from server xxxx@cloud:7178. 72

[apTater]

Hi, I'm seting up a plastic client Plastic scm cloud. On the website I can get to my account and see that I'm part of the team.
In the Plastic scm client I can check my credentials and it says that yes, I'm indeed part of the team.
When I try to create new repository and insert the team(cloud) name (teamname@cloud) it tries to collect the data for a minute and then says unknown command received from server teamname@cloud:7178. 72

It has taken us two days already so any help to be able to use this product is welcome.
