Beryl AX wireguard client not working

So I have a wireguard server(on beryl ax) setup at home. One day while travelling overseas, my wireguard client(also on beryl ax) turned orange in the admin panel. Couldn’t connect to the internet obviously Im guessing killswitch was turned on… I asked my friend(back at home) to restart both ISP modem and beryl ax(my wireguard server). And boom. my wireguard client turns green(in admin panel) and works again! What do you think was causing this? ISP modem? Or beryl ax(wireguard server at home)? This already happened twice.

Hi,

  1. When the travel router WG client is disconnected, please export the syslog at this time and share with us.

  2. When the VPN is disconnected in travel router, not restart the home router WG server, use other WG client APP (such as test in the PC, phone, etc.), is the WG VPN connection normal?

  3. When the VPN is disconnected in travel router, is the home router Internet ok? such as ping www.openwrt.com on Luci:

  4. Is home router WG server enabled DDNS? When the issue occurs, check the DDNS test to see if the resolved IP is WAN IP.
