Been in Brasil for months, wireguard worked completely fine with the setup in the image.

Have moved to another city to a friends house, plugged in the slate via the same setup as in previous city, wireguard no longer working. Need to resolve this by Sunday ideally, can anybody help?

logs below:

Sorry for this issue, please restart the DDNS service on the VPN server side, many users have verified that this method resolves the DDNS issue. If this doesn’t work, please send me your DDNS domain via private message.

If you need a temporary workaround, please manually modify the Endpoint in your VPN client configuration to your public IP address. For example: change Endpoint = xxxxxx.glddns.com:51820 to 1234567:51820. However, please note that this solution may not work for dynamic public IP addresses.

How can I do this without access to the UK server side? I am in Brasil

This will not help you now, but on my remote GL iNet routers, I have my routers reboot daily using cron, as it clears these types of issues if they ever occur. I have been traveling for years now, and it keeps things working.

Please advise how to send private message, thanks.

I still have not seen my DNS name propogated or been able to resolve with a reboot. Pls advise how to direct message.

Thx

@amowagou @hopeless Both of you can use PM now by hovering over usernames.

I am having the same problem, had wireguard working for weeks and yesterday it stopped working, I have restart the wireguard server router and still have no way to connect, what can I do?

9

Please disable and re-enable DDNS on your server router.

10

It worked! Thanks

11

Hello,

the solution did not work for me. Please advise.
Thank you.

Hello! I think there is an option to schedule reboot on GL inet admin. Is it worth doing this? Will it keep the DDNS refreshed?

13

Rebooting restarts all processes, and can clear things like network issues and memory leaks. I do it on my GL iNet routers that run remotely and have been doing it for years.

Many peoples may tell you it's not necessary, but I find it keeps my routers working.

14

It worked, however for some reason the time zone is not showing as UK any more. When I plug Ethernet into my mac, it used to switch to the uk VPN time zone immediately which it doesn’t do now. The client router time zone is set to London/Europe. How do I fix this?

15

I tried again and waited long time between disable and re-enable the DDNS and it worked now.
Thanks.

16

Should there be a "sync" button on the router's admin panel?

17

Yes but that syncs the Brasil modems time I believe….

18

I tested it earlier and it synced to Brasil instead of the server device

19

Great tip. I will need to get someone in England to login to the admin panel and set up the daily reboots. Is there a way of accessing the server admin panel remotely?

20

By using GoodCloud. If your device isn't added to GoodCloud so far, the person who needs to enter the admin panel (physically on the remote area) should enable it as well.

Or you might try to get the current WAN IP (maybe you have some other systems at this location which might log the IP somehow?) and connect via WireGuard then, using IP instead of DDNS for this time.
