Either your partner isn't connected to the internet or your partner's TeamViewer isn't running yet.

I'm recently getting this message when i try to connect to another computer on TV "Either your partner isn't connected to the internet or your partner's TeamViewer isn't running yet."... any suggestions on how to fix this? I've been using TV for years with no issues until now.

Looking for a different issue, but i saw this thread. If anyone still needs it:

TeamViewer uses multiple TCP ports, including:

TCP/UDP port 5938The primary port that TeamViewer uses for outbound connections. TeamViewer performs best using this port.
TCP port 443TeamViewer will try to connect over this port if it can't connect over port 5938.
TCP port 80TeamViewer will try to connect over this port if it can't connect over port 5938 or 443. However, port 80 is only used as a last resort because it's slower and less reliable than ports 5938 or 443.

For mobile apps, TeamViewer uses port 5938 for both Android and iOS. If 5938 is blocked, TeamViewer will fall back to port 80 for iOS. You don't have to open any ports in order to work with TeamViewer. TeamViewer determines the optimal type of connection when establishing a session. In 70% of all cases, a direct connection via UDP or TCP is established. You might see different ports being used within your network surveillance tools because they work by finding a free port and then sending packets out on it.

To check port status:
Likely, the best way to check is with an elevated (Run as administrator) cmd window, with the command "netstat -b". This results in the following report (you have to search the list…)
Proto Local Address Foreign Address State
TCP 127.0.0.1:5939 MMBDTWin10:56878 ESTABLISHED
[TeamViewer_Service.exe]

127.0.0.1 is the local IP for your own machine. I am not currently running a TeamViewer session, but i suspect the 5938 port will show up if you are, along with the IP address of the remote machine you are trying to access.
You're a little bit on your own with this, as i'm not sure if port 5939 is used as a secondary port in general or is a connection back to the TV site, like for checking your license, or knowing when your remote site has started TeamViewer and phoned home… Would be a good thing if TeamViewer support would supply the full answer, since not everyone knows what TCP, UDP, or ports are, what they mean, how they work, or how to figure this all out, so you should specify in your question what your own OS is and what the OS is of your remote machine; then they can give you the precise commands to run to answer their questions. Linux has way better network monitoring programs built-in, so if you know how to install and run Linux on Windows or how to use the terminal commands on MacOS, your life will be easier trying to debug these issues. There has to be a way to tell if a particular port is blocked by your Windows firewall settings, but in my brief attempt to help answer this question, i don't see a good way in the firewall to check this. On Windows, you can also look through your Windows Firewall interfaces and check to see that TeamViewer in and out connections are allowed on both Public and Private networks. That helps you, but i don't think that is what TeamViewer support is asking for in this situation.

I have this issue too. I could've swore I setup everything properly at home. And on the road I get this same error as everyone else writing in. Internet definitely works at my house right now because if it didnt, I'd be getting alerts on my phone to tell me otherwise.

anything besides the ports and connection settings which was never explained how to obtain them. The person the other computer shows that they are connected but then I try to connect to them, it says they are not connect or do not have their team view open. How does that make sense?

I get exactly the same message. TV was working fine with a particular computer, used it often, then from one day to the other it stopped working an giving me that untrue message. Nothing changed on either computer. It still works the other way around. Reinstalled TV on both sides, no change.

TV works well on other PC´s, just not that one.

Hi,

We have this issue with all our remote computers and can only be solved by restarting the computer. Defeats the purpose of remote working as we do not know when the restart may be required and someone needs to be present to do the restart.

Any solutions for this?

We have 10 licensed users having this issue on and off invariably on mondays. We are on Windows 10.

I had this problem with my parent's pc, which has been very frustrating

Eventually when a younger member of family was able to visit we found out that their partern id had changed - we have no idea why or when but once I used their new partner id I could connect - but when it was really needed during lockdown could not use

I am getting this error after TeamViewer attempts to re-launch in elevated mode on the client when logging in with the optional WIndows admin credentials mode. It appears the TeamViewer never gets re-launched.

Unable to connect

"Either your partner isn't connect to the internet or your partner's TeamViewer isn't running yet."

"Please tell your partner to check his/her internet connection or to start TeamViewer."

I use TV to connect to family & friends in Toronto, Canada from my location in L.A. The family friend just finished installing TV adn we are emailing each other every 5 minutes while trying to resolve, but I keep getting the msg that her side is not on the Internet when it obviously is. She uses ethernet connection while I am high speed WiFi.

btw: The family friend is on Windows 8.1 (while I use Windows 10) and recently had her laptop serviced by Geek Squad.

I have this issue found on yesterday. It was running prefect till last Friday. When I was tried to remote my office PC. It was just connecting.......but not success. Today, when I was back to office, it was still not working. But, when I connected my PC via WiFi, everthing was working properly. However, this was not working when I used back the complany wire network (this netwrok could access to internet when using web browser). Anything got wrong?

I had to get a new computer and was trying to get TV up and running. From my new computer I can see all my other ones, but from this is the only one I can not see my new computer. I can use TV to go to another computer and I can see all of them so I know the internet is on and it is working. Any suggestions on how to get this machine to see my new one. Thanks

Can you please explain what 'connection settings' you're referring to and provide instructions on how exactly how to see if the ports are open?

Hi @vmconrad,

Thank you for your post.

As the message shows that: Either your partner isn't connected to the internet or your partner's TeamViewer isn't running yet. Can you kindly check for the internet connection and TeamViewer is working fine for remote connections please.

Hope it helps.
