Environment info

• Duplicati version: 2.0.4.5_beta_2018-11-28
• Operating system: Windows 10 x64

Description

At least once every day, duplicati.gui.trayicon.exe connects to a known Microsoft server (IP = 13.107.4.50). I wonder if people are aware of this, and whether it can be addressed. It looks a lot like Microsoft extended its telemetry to .NET applications as well, but I'll be the first to admit that is currently no more than speculation from my side.

Steps to reproduce

1. Use a firewall like simplewall that blocks 13.107.4.50 / CurrPorts / Wireshark
2. Start duplicati.gui.trayicon.exe
3. Wait a few seconds
   Unfortunately the connection is not attempted on every start, just the first start every day.

I can see the same behavior only with Microsoft's Remote Desktop client mstsc.exe.

Does this occur when using just a local backend, or even when no backups are configured?

[ltGuillaume]

I am using just a local backend. This is basically what I do from a batch file:

set Duplicati_Home=%~dp0Data
duplicati.gui.trayicon.exe
start http://localhost:8200

My current setup has 0 scheduled backups, i.e. they're all run manually.

I've set up a separate portable instance without any backups. I'll run it periodically to see whether I can catch the same behavior.

Not sure if there's anything we can do here. It would be interesting to see if this occurs on Linux/Mac as well.
