Mwan3 2nd wan not working

Installing and Using OpenWrt
1

I followed a tutorial on youtube trying to install 2 wan at my linksys wrt 1900AC the configuration went smooth. and i added the 2nd wan and it has an ip as dhpc from another isp ,
the problem if the main wan go down and 2nd is up i have no traffic it seems like 2nd wan doesn't work.
actually i don't need balance i just need if first network go down i want the 2nd network replace it .
note am very new using openwrt
please anyone can help
thanks

I would follow a fail over configuration in https://openwrt.org/docs/guide-user/network/wan/multiwan/mwan3.
Your mwan3 config file is missing the wan / wanb only configuration for that purpose.

I suggest you remove wan6, since it is not working anyway, as well as the rule for v6.
