I have installed TeamViewer on my new Synology DS720+ and started the TeamViewer app on the NAS. It supplies an ID and password for assignment. I have added the device to my account with these credentials.
However, when I try to connect to it either via the web interface or the app, it says "authentication rejected".
I have tried as many things as I can think of and searched the help, but I cannot figure out why I am getting this issue.
I am running the latest version of TeamViewer with the new interface and Win10 Pro. Everything is up to date, including the NAS.
I am using a remote connection (not local).
My Internet connection is via a Virgin Media Superhub3 in modem mode, and I am using a Synology RT6600ax router. I can use TeamViewer to access the computers on my home network without any problems, and my DS720+ is on the same network as these - so I am fairly sure it's not a network issue.
Would you be able to advise as to what I can try next, please?
Many thanks in advance for your time.
Kind regards,
Ben.
