hectorricardo:

Android device is connected to the same Internet connection as in scenario 1 and 2, so this is not a carrier network issue.

So the Android is actually connecting to your wifi and share to via USB?

hectorricardo:

How do I share it to you? Can you provide an email?

Just share with PM.

Correct. Android is connected to wifi. However, before upgrading to 4.1.0, it worked with both Wifi and Mobile Data.

Everything (all four scenarios) was working with the pre-installed 4.0.3 firmware. Issues started by upgrading to 4.1.0

Did you keep settings when you revert back from 4.1.0 to 4.0.3?

If you didn’t keep settings then it should not relate to firmware version.

I did keep the settings. The Wireguard config is in place.

Pls try clean installation and Configure again.

I have done that several times. I have done the following:

Pressing the outer hardware button on the router for 10 seconds.
Using the admin UI, clicking on the “Reset Firmware” button.
Install a new version of a firmware (4.0.2).

The issue is not solved with any of these steps.

I was planning to buy an AX next week, now I’m unsure. Maybe the Flint would be safer

So seems that the wireguard does not work on your Andriod tethering now. Now sure what is the problem.

hectorricardo · 2023-01-07T17:30:45.696Z

Not only on Android, but also with the iPhone.

Can you try change mtu as in this post

Beryl Wireguard VPN Client Has Randomly Stopped Working (Log included, Please Help) Technical Support for Routers

Update: We changed to a smaller MTU, the connection gets successful. Let’s see if there is an improvement. [image]

hectorricardo · 2023-01-08T20:50:40.644Z

I did, but no success. Still same error:

Today I worked with @hectorricardo to solve the problem. Several problems are identified.

The wireguard config from Starvpn use domain name as endpoint. The domain resolves to several IP addresses. Different network will resolve to different IP address. Some IP addresses does not work. When hard core to certain IP address, it works OK. So this is definately a problem of Startvpn. This is verified on windows pc as well.
Two bugs identified on our firmware: (a) The firmware does not work well with two IP address in wireguard config; (b) not be able to edit wireguard config in @hectorricardo’s macbook browser. I can edit in my Chrome though.

Luckily I found this topic.

New GL-AXT1800, facing EXACTLY same issue.

WG server is operational, same config exported to mac client works without any issues.

What I have tried:

replace server hostname with IP to exclude DNS related issues;
change VPN settings on AXT-1800 as some advised in the thread.

So far nothing helped, I am still getting REKEY-TIMEOUT.

You can send details to me to check.

All the issues I checked has a different reason.

Jester · 2023-01-17T02:44:29.491Z

@alzhao thank you - I’ll do that. What details you are looking for?

alzhao · 2023-01-17T04:42:23.169Z

Pls read this post 4.x Wireguard REKEY-TIMEOUT troubleshooting

You can pm me your wireguard config, detailed network setup and issues to check. If the problem is you cannot connect to Wireguard at all, I think I can find the problem quickly.

Jester · 2023-01-17T08:12:54.465Z

Sorry I don’t see how to PM on this forum. Am I have Pms disabled?

As for the configuration - I have set up Wireguard VPN on Raspberry using pivpn scripts. The raspberry is at my home network behind NAT, so I set up port forwarding for TCP/UDP. Wireguard uses non default port (but from very same range).

Moved AXT1800 out of home network and tried to connect - got REKEY-TIMEOUT. Thought something wrong with port forwarding, so brought it home, changed server name to local IP (192.168.1.x), tried same - got same response REKEY-TIMEOUT.

Then I decided to test the VPN - installed Wireguard client on my laptop, used same config as on AXT-1800 - and it connected in a second. Wireguard client on laptop works even when I am outside of local network, so port forwarding proved to be working fine.

At home AXT1800 is connected via WiFi to local network(192.168.1.x). All devices are connected to AXT1800 network (192.168.8.x), there is no problem in connectivity whatsoever.

Let me pm you and you can reply me.

I’ve been following this thread for a few weeks hoping to find a solution. I also have the REKEY TIMEOUT issue. Only using mullvad.

New Slate AX 1800
Tried multiple firmwares including the latest 4.2 beta 2.
-Previous versions didn’t let me pull a mullvad config at all when putting in my account number.
-4.2 allows me to pull the mullvad account from the settings page, but still have a REKEY TIMEOUT when trying to connect.
-OpenVPN works
Using the router at home, not 4G/5G
Not using IPV6
Not using DDNS
Commercial mullvad service.
Not using Adguardblock

Can you pm me to help resolve this issue?

alzhao · 2023-01-20T01:42:55.469Z

I sent you a message.
