Wireguard (Mullvad) not connecting after Update 3.025 (SLATE GL-AR750s)

spamatiki · 2019-07-07T22:08:16.022Z

After updating to firmware v.3.025, SLATE GL-AR750s stopped connecting to Mullvad-Wireguard.
All connections time-out.

I updated from v.3.022 to v.3.025
Without “keep Settings”
I entered Mullvad-Usernumber by hand
All Mullvad (Wireguard) config-files were accepted
After hitting the “Connect”-button, nothing happens, all connections just time-out

To check if it was a network-issue, I installed openvpn-Configs (NordVPN), and those connections work just fine.

With version v.3.022 on my SLATE, Mullvad-Wireguard was working for allmost a year now, after the update it’s broken?

Any help is appreciated

Can it work before updating firmware? Would it caused by your account is expired?

It worked perfectly before (with firmware v3.022).
Mullvad-account is not expired.

spamatiki:

Mullvad-account is not expired.

Had you tried it on your PC? You can use WireGuard on PC with TunSafe.

I cannot connect to mullvad server either. Even using their windows app. Seems that this is they server problems. I will ask their tech support.

I found the problem.

Key limit is exceeded. I have to login Mullvad and remove all my old keys. Then I need to add Mullvad again and it works now.

@ alzhao
Great catch! That was exactly the problem! Thank you!

The point is: Each time you reset/upgrade your (gl.iNet)Router, and re-install Wireguard/Mullvad, the Router requests a new “Mullvad-WireGuard key”.
I have 3 routers, and upgraded all their firmwares, so I ran out of keys (3old ones & 3 new ones … makes 6 keys … but only 4 keys are available with Mullvad).

please mark the issue/post as solved.

Thanks everyone for the fast help! Great as always
