Steam Guard Recognizes my PC as new Device at EACH login.

[Lord Gorzul]

Every time I open steam the past day or so, I get steam guard telling me that I am logging in form a new device.
The biggest problem with this is that I am a heavy trader, and even an hour of trade lock can be problematic for me, let alone weeks.
And since each time I log into steam it says im using a new devide this is even more of an issue. What kind of bug is this?

Make sure your device is protected by Steam Guard for more than 7 days (which I am sure you know is a Marketplace Eligability thing)

Try logging out of other devices and make sure that Guard hasn't registered an unauthorised device connecting. If it is then your account security has been breached and a change of password is highly recommended.

The issue is happening on my main PC which has had steam guard for over a year, ever since it was introduced. I never had any issues. I turned off my pc for 3 days as I went on a business trip, upon coming back, I get the steam guard message when I logged into Steam.
This morning I logged into steam again, and I got this again.
Basically every time I log in now, im getting that.

This is the case for both browsers I use (Chrome and firefox) as well as the client.
Interestingly it only affected my main account which is this one, and not some old account I have which I can log into from the same PC fine without steam guard being reset.
