I am facing some issues with the MWAN3 configuration.
I had already configured MWAN3 in OpenWRT, and the failover configurations were successful; only load balancing was left. Suddenly, the configuration was removed.
I reinstalled the package and tried to do the configuration from the beginning. But now the issue is that once I do the configuration on the Luci interface, It gets deleted as soon as I apply the changes
Yes, it seems you have reached its limits.
Also when you paste some console output avoid using images and prefer to paste in preformatted text (the </> button).
