18.04 Teamviewer problems

[Adam_GUI]

robins@robins-desktop:/opt/teamviewer/tv_bin/script$ ./teamviewer

Init...
CheckCPU: SSE2 support: yes
Checking setup...
Launching TeamViewer ...
Launching TeamViewer GUI ...
robins@robins-desktop:/opt/teamviewer/tv_bin/script$

No error and no draw, huh?
I'd side on purging the program and reinstalling.

"sudo apt-get purge teamviewer"
This will remove all your teamviewer configuration files along with the program files.

Then, reinstall and try again.

I reinstalled, and tried again. Sadly I have the same problem ie GUI not loading.

Could I please have some help with this correspondence:

I have been having correspondence with Teamviewer over my inability to load their program in Ubuntu 18.04.

It looks like you are using some sort of firewall or other tool that limits network access to localhost, e.g. iptables, SELinux, AppArmor or similar. The only thing I see is that our processes are unable to connect to each other. On a new, stock Ubuntu installation you should not have such

My response:

Re: Further log files
I can only see in synaptic the Ufw standard firewall as being installed. I can not find it in the application lists as a program to run. The IP tables are ticked as being installed (Ufw is the front end of them) but I do not know what they are set at.

I will take your suggestion to the Ubuntu support conference and see if anyone can help me open ufw and also give me some insight into the apparent existence of a firewall that is blocking TV. It would help me if you could propose some command lines to discover what is doing the blocking.

What is likely to be blocking TV13?

I have just written again to TV as follows.

Firewall check
I have just run the following. Does it back up your contention that the firewall is blocking TV13? Please bear in mind that my problem with TV13 is at the loading stage when it is unable to load the graphics.

In the hope I get a solution to this TV problem I have opened a new topic just on the firewall aspect at

Are you using a VPN? Just read another post where the person fixed their TV13 by disabling VPN.

[Robbyx]

Thank you. Disabling my VPN appears to be the solution.
