Got ID changed on a headless machine..help needed

Hi,

We have several headless machines running ubuntu 16, with teamviewer 12 (full version) installed. These are deployed remotely to collect data from sensors, so I have no phisycal access to it. I've just found out that one (at least one, I have to check if other machines are affected as well) got it's teamviewer ID changed, so it became unreachable!! No update has been done.. this just suddenly happened.  We have a business licence.

We just added the machines to computer and contacts list, without assigning to the account.. does it make any difference? In the past I used to have an option to add the remote computer to the account directly from my computer, but now the option is gone and the only possibility is to do it from the remote computer, which however requires to confirm by receiving a mail.

Any help ?

Re: Got ID changed on a headless machine..help needed

For future readers..I ended up opening a support ticket, this is the outcome..

1) Support team is not able, due to privacy regulations, to tell you if your machine has got the teamviewer ID changes, nor is able to give you the new one.. so if teamviewer was the only way to connect to a remote machine for you, there is no option for you that going onsite..

2) Teamviewer ID is not supposed to change, but there are some cases where it can happen, for example in case there is an hardware change. Sometimes there is a switch between 2 IDs, and teamviewer team can help you fixing one of them (although they confirmed me that on linux is more difficult). In my case 4 of my headless remote machine just changed ID definitively, so nothing to do. My machines use a LTE dongle for internet connectivity and some modification on the dongle itself (critical firmware update that are enabled or something else) could have triggered the ID change. It's not sure, because teamviewer logs are too recent and doesn't show the ID change, so the real cause it's hard to identify.

Solution in my case is to use this simple tool:

You get an email every time teamviewer change ID, with the new one!

Re: Got ID changed on a headless machine..help needed

Hello @rok

Thank you for your message and welcome to the TeamViewer Community! 🙌

You are correct - this should not happen. A TeamViewer ID is unique and dedicated to every TeamViewer installation.

Let me suggest you the following:

  1. Delete the impacted device from your computers and contacts list
  2. Assign the device to your account, it will add the device automatically to your computers and contacts list

...and check if the situation stabilized.

I hope this could help. 🍀

Looking forward to hearing your feedback.

Best regards

Jean

Re: Got ID changed on a headless machine..help needed

Hi JeanK, thank you for your support

So.. adding the remote computer to "computer and contact list" is different from assigning it to the account?

Reguarding the link you provided.. I have no option (I remember this option was there time ago) in my teamviewer 15.10.5 (ubuntu) to assign the device remotely, should I connect to every single device and confirm then by mail ?

Third and most important question..How can I do all these things If the device is headless and remotely installed ? I discovered these ID changed (2 at the moment) only thanks to the fact that we have other computers in that local network.. but we have single computer who has probably the same issue and cannot connect in any way!
