Hello, i have a problem with acces to any site via https/ http, the client vpn and the server are connected I see the traffic up and down, I used WhatsApp application for messaging and calling its works fine, only browsing is not working?
Any solution please ?

The server works fine before, just when I switch off my router and switched in and all is down now for me after reset and created my vpn WireGuard I get the connection problem with the browsing

It looks like the DNS not works.

  1. Does the VPN Client router enable the AGH?
  2. Try to manual config an DNS server on the GL GUI > Network > DNS.
  3. Reduce the WG MTU on GL GUI > VPN Dashboard > WG Client > Options.

Thanks for your return, but my DDNS résolve correctly, I get the ip from my ISP from WireGuard server.
I have the version 4 of mars 2023 with killing switch option in client vpn to keeep this option.

I test now only with my WireGuard application in my laptop and still have the same problem

Where can I found the Network / DNS is not present in the current version please.

It looks like probably the VPN server issue, please contact the VPN support.

DNS is different with DDNS.
It may be a DNS issue since it unable to open HTTP/HTTPS website.

What is the equipment model?
Please upgrade to the latest firmware version.

I have a GL-SFT1200- 921 with 3.216 version.
I can connect to the IP of server router from my laptop via WireGuard application, I see the ip public for the ISP operator and also, thé transfert data Up and down, but always not acces to internet browsing.
For the upgrade I want to keep the kill switch for this version under vpn client.

The killswitch already supported in all firmware version, including the latest version.

Try upgrading the latest beta firmware for the SFT1200:

Could you access the browser webpage normally with the laptop WireGuard application?
If not, please check your VPN profile if there is the DNS parameter.

It's not clear from the above. What device are you running the Wireguard server on.

Try to directly input a custom DNS server IP on the virtual network card wireguard to see if it works well.

If are the LAN clients connected to the SFT1200 router, internet browser work well?
