I'm new here and my device is ASUS RT-AX52. I have no idea how this can be replicated, as after a casual reboot, I didn't notice for a while but when I was outside in a cafe, I tried connecting to my wireguard configuration, it didn't work. To clarify, it did work before the reboot. If you'd like more information about my wireguard configuration, feel free to ask.
We'll need to see the config to understand what is happening. Also, it would make sense to upgrade to 25.12.4 which was just released.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/firewall
wg show
date
Ah I found the error. I checked in my logs and I saw it was a configuration parsing error. I have it easily fixed. Thank you for the markdown hint! Also I will update soon, thanks for reminding.
