Bug: Domain update status 'Unset' when it exists in system hosts file

[brammp]

TLDR: When the domain exists in /etc/hosts the domain status gets stuck on 'Unset', and is not updated when using binary on Linux

1. Is this urgent: No

2. DNS provider(s) you use: OVH & Custom

3. Program version: 2.9.0 (commit 78f30614b1d085ef6bfbfce92b0e45ca0204f42a)

4. What are you using to run the container: N/A, using the binary on Linux

5. Extra information:
   When the domain entry is removed from /etc/hosts everyting works as expected and the ip is updated after restarting the binary.
   To replicate make sure updates.json is empty.
   Also tested the Windows, MacOS/Darwin versions and Docker, and these are not effected.

I had the same issue with a persistent unset status using docker and qmcgaw/ddns-updater:v2.9.0
I temporarily fixed it by using an older version.

I have the same issue. I was working fine some weeks ago
