Teamvierer-Host working only one time after enabling

Hi @all,
i need a little help from the specialists...

I've installed the Teamviewer-Host Plugin. (on OMV 3.0.99)
After the Installation finished i've enabled the Plugin and saw directly the given ID for Connection.
With the reset Button i've change the Password to a one i like.

First connection Try after that worked fine from my Laptop.
Then i restarted the System ....

After that, the ID has changed !
Anyway.... I tried connecting with the new ID and my password , but connecting
was not possible 'cause it says that Password might be wrong.
Tried to change the Password with the reset button and reconnection. Did not work.
Then tried resetting password with "teamviewer passwd xxxxx". . Did not work either.

Then i reinstalled the Plugin and the above described process was the same.

What am I Doing wrong?
Any help or Tip?

Thanx

Bye,

Monitor is always connected.

Zitat von raulfg3

each time do you reboot are a monitor connected or not?.

PD: Teamviewer need a monitor connected to generate the ID, so if you do not have a monitor atached, on reboot, you do not have an ID.
