Done I can't join servers

When I start Galactic sciences , I can't join the Mym's hub and the server , my luncher don't find it and if I try to join it's say : " Timed out"

 

With a luncher without mod or with your vanilla in your luncher ?

 

I just do this , my lyncher as crash but now I can connecte to your servers thanks you



Edit :

I try to reconnect after but it's don't work again , I try to log into the hub with a vanilla luncher but it's don't work and I can't play to Galactic Sciences server
