Connection stuck while using Samsung Remote Test Lab

Question

I want to track down a bug on Samsung Devices using Samsung RTL. Sadly i cant get that client to work on my System (macOS 10.13.1):

It just says Connecting...
Nothing happens from here.

Steps i did to come here:

• Downloaded and installed newest JRE from Website: https://www.java.com/inc/BrowserRedirect1.jsp

• Enabled Java for Browser and Web-Start-Apps in Java Control Panel

• Added https://img-developer.samsung.com to exeption list

• Checked for Port 2600 using Network Utility: https://support.apple.com/en-us/HT202790

• Create Samsung Developer Account

• Reserving an Device (Galaxy S6)

• Download .jnlp-File and run it

Answer 1

Customer Support has answered to me. Seems like i have just selected a bad device. I chose another one and it worked :)
