Flint Stuck in endless loop on Wireguard start

NLCJohn · 2022-11-17T21:56:37.566Z

@alzhao the issue is that we can’t connect at all using Wireguard, the outgoing configs are not the issue since OpenVpn works and portforward work.

It is an infinite loop where we see the timeouts.

strange but if you will manually assign dns servers (to public google for eg.) and disable ipv6, wireguard connects without any issue. when dns is set on auto, and/or ipv6 enabled… endless loop (rekey blah blah).

Oh dam is it fw3 to fw4 migration issue again
If you are on openwrt 22.03.x NFTables are starting to be used. Config files that are created pry to 22.03.x use IPtables. Best solution I have found is set up everything from scratch and make a config based on that.

akki:

It is not our job to provide you with configs.

If you have issues need to provide something. Otherwise how to solve.

I supported many many users. They decided the method how to help, e.g. providing config (usually for openvpn) or do remote check. I solved many cases related to Wireguard already.

akki:

Stop pointing fingers at others

Sorry for my bad English. What do you mean?

akki:

Clearly its your device/firmware issue. Own it take responsibility and fix it rather than asking people for configs. I can assure u that u will never be able to replicate/or the config will be invalid if you are not willing to own ur mistakes

I didn’t say the firmware has no issues.
I do replicte the problem and solved some cases. The TIMEOUT message is a very general message and it could relate to a lot of different cases.

Besides it might be the iptables to nftables issue,
Could anyone check what the result is if you remove the preshared key option both from server and client?, I believe for openvpn that is a tls key.

When I hosted my own openvpn server a really long time ago, it only complicated configuration, you want the config as simple as possible to get a start.

I got a case that this happens on ProtonVPN Wireguard. It does not come with a pre-shared key.

I am testing ProtonVPN Wireguard now.

Same issue here - works on the laptop itself, but can’t connect my router.

This is my endless loop

I have two wireguard VPN servers (created with pivpn) on two different raspberrys, but after updating to the last Flint version I can’t connect to them, but they are working as I can connect using MV1000 and using the android wireguard client

Any ideas ? Do you need any extra info?

K3rn3l_Ku5h · 2022-12-12T20:54:45.255Z

Are you using GUI of LuCi for setup?

Serd · 2022-12-13T07:23:12.733Z

I used GUI for the setup

alzhao · 2022-12-13T09:38:11.965Z

It does not connect at all, or it connect and break?

If it is the first case, may need to verify the config once again on your phone etc.

If you can, send me one config in private message.

Serd · 2022-12-13T20:13:34.546Z

it doesn’t connect
it works in the MV1000 and in the phone

blindman · 2023-01-14T03:50:23.660Z

I am getting the same problem

tech333 · 2023-01-16T01:16:43.982Z

Same. Did anyone figure this out? @alzhao @Serd

K3rn3l_Ku5h · 2023-01-16T15:28:54.245Z

Update Uboot
Do a clean install to 4.x using Uboot
Setup.

Most of the issues is caused by keeping settings

Back ups that are created in LuCi seem to work (don’t reuse a backup config file generated in 3.x

tech333 · 2023-01-16T21:57:23.513Z

Thanks for replying. Looks like it was a config file misconfiguration with the public key. I got it working, but now I keep getting this in the log, is it normal?

K3rn3l_Ku5h · 2023-01-17T01:18:51.664Z

Who is the VPN provider? alzhao I think did mention something about certain VPN that the keypair did not work. Also it might be a issue in you vpn config file.

Not sure if this is related:

Slate AX (GL-AXT1800) Wireguard Issue (REKEY-TIMEOUT) Technical Support for Routers

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 wi…

tech333 · 2023-01-17T04:22:09.639Z

It is my own wireguard server router on openwrt 23.03.03 at a different location setup using the wireguard server setup wiki on openwrt. The DNS is the main router IP address, which the openwrt server router is behind. Here is my config file for the client:

[Interface]
Address = 192.168.9.2/24
ListenPort = 51820
PrivateKey = yGzJjxxxxxxxxxxxxxxxxxxxx
DNS = 192.168.4.1

[Peer]
AllowedIPs = 0.0.0.0/0
Endpoint = exaxxxx.duckdns.org:51820
PersistentKeepalive = 25
PublicKey = Eorq+jDgkxxxxxxxxxxxxxxxxxxx
PresharedKey = es79xpyxxxxxxxxxxxxxxxx

alzhao · 2023-01-17T07:13:56.798Z

Pls check if your ddns resolves to the same IP everytime.

I also observe that your used 192.168.9.x and 192.168.4.x subnet. Pls make sure these are valid.

If you cannot make it work at all, it may be your server side set up.

Correia · 2023-03-03T20:30:20.157Z

I have the same issue. It stays in a loop trying to connect.

In my GL-MT300N-V2 everything works fine.

I just upgraded to a GL-MT2500A and I cannot connect to my Wireguard VPN.

I am using VPN Unlimited as a VPN provider.

And I have an additional issue that I do not know if it is related…

When I stop my failed wireguard connection, I lose connection to the internet. I need to restart the router in order to get connection to the internet.
