Only one Client Works (Webbrowser or Client)

Seafile Server
1

Hello,

ive got a huge problem with my connection.
When i start my server, first i got with ./seafile.sh start and then with ./seahub.sh start-fastcgi .
My problem is, when i start with this paramters on the upper row i cant connect threw the client, webbrowser runs well.
When i start the seahub with ./seahub.sh start then the client works well and the webbrowser doenst work.
Client error: Connection refused
Webbrowser error: seems to be in a loop, its just loading and never ending with a error in the browser.

location /media {

}

So, i hope you can help me, the error logs are empty, firewall ports are okay and setted up.
