can not Registering my device in EventGhost

The event ghost was perfectly connected with the join in my
Device
, but after I made formations for my computers I tried to link with the join and followed the same steps, but the message Invalid Key appears to me and I repeated the steps many times to no avail and I don't know what I'm supposed to do.

 

I also have an invalid key

 

No. Still showing 12:29:30 Result from sending request: Your key is invalid. Please check your key and try again.

 

I go to a personal url from autorote. I copy the url with the personal key to eventhost, but it still doesn't work

UPDATE: all works. thx

 

I used a personal url.
