Hi All,  as a Linux sysadmin I am using TV but find dificulties to set it up on CentOS
On a Linux CentOS machine after intsllation teamviewer setup fails 
- OS : CentOS Linux release 7.6.1810 (Core)
 
- GUI: Gnome 3.28.2 (gnome-classic) 
 
- firewall ports opened in both directions : ports: 80/tcp 443/tcp 5948/tcp 22/tcp 5900-5910/tcp 44996/tcp 5948/udp 5900-5910/udp
 
- SELINUX disabled
 
- DNS resolution works toward master1.teamviewer.com - master6.teamviewer.com
 
 /var/log/teamviewer14/TeamViewer14_Logfile.log
[Logfile as been removed]
please let me know if you have any hint what could cause this issue.
