DNS Bad Config Error / DNS check failure

[BaGamman 4]

Hi,

this probably has been answered a million times, but I started a couple days ago to have an issue with AirVPN on ones of my computers.

Long story short, it started to fail the DNS check. When I try to deactivate this check, the client is connected and I can perform a certain number of non-Browser action such as pinging servers with my CMD, but anything I do with an Internet Browser fails with the DNS_Probe_Bad_Config error.

I'm kinda in the lost. I tried to change my Ipv4 DNS, reinstall Eddie-UI and add a bunch of free DNS addresses in the setting, but it doesn't work.

So, a little help for a long-term customer, please ?

EDIT: Ok ? It seems updating to v2.18 managed to fix the issue. Maybe an update made the v2.17 incompatible in some way ?
I'm keeping this open for the record, it might help some.

Below, the logs from what happens when the DNS check fails:
