Update April 2018 : I've tested TeamViewer 13 on Ubuntu 18.04 LTS (running on Xorg) and the application installed correctly by clicking the .deb file. TeamViewer seems to work as expected.

Update August 2018 : TeamViewer 13 has left the preview state and became a regular product.

Update November 2018 : TeamViewer 14 was released and is being made available for Linux.

Users who experience problems with the new edition, may want to follow the discussions in the TeamViewer - Community TV General | Community TV Linux | Community TV TeamViewer 13.

starting today, i'm getting the error "Not ready. Please check your connection" after installing version 14 of TeamViewer.

I have followed all the tricks available, but nothing seems to work.

I've check the network availability for TeamViewer services, and it seems to be working fine.

I request somo help please. Via console on the web i can connect. I also can connect on my mobile. Only in my PC, i cannot!

I am trying to use TeamViewer 14.1.3399 on Arch (manjaro) Linux at home, to remotely connect to my work computer, which is an Ubuntu Linux system also running TeamViewer. I have all the login credentials and stuff, but my home system says "Not Ready. Please check your connection". It won't allow me to log in or attempt to connect to anything.

Internet is working fine. I don't have a firewall for outgoing connections. I am able to ping master1.teamviewer.com as well as other servers. If I tell it to accept incoming LAN connections, then the status changes to "Only LAN connections are possible" but that is useless, since the computer I want to connect to is remote.

There is a setting "assign to an account" which I have not done, since this is my home computer and I'm not interested in allowing remote management or access to it. I can't find any explanation or documentation of this setting.

Hello. I've been having trouble with teamviewer ever since updating to version 14 with connecting. Please let me know what I can do in order to utilize teamviewer again.

No matter what I do, it just gives me an exclaimation point, complains about a proxy and can't connect.

I've confirmed I can ping master[1-6,9].teamviewer.com

Teamviewer is established and/or listening on ports 2379,2378,6039,5938,61715,5353,51716,5353

I've reinstalled clean twice.

Added exception rule to windows firewall

Disabled the firewall

Rebooting router/modem

tried running my computer off 3 different internet connections (from 3 different ISPs)

I'm running windows 1809 Build 17763.194 (home edition)

Specs:intel i7-4810MQ (2.8GHz),16Gb RAM, GeForce GTX 860M

In general under options, if I select "accept LAN connections" I can accept in-network connections.
