Happy new year mate.
Last black friday I bought two gl-inet routers.
BTW that has probelm on admin panel.
It was too slow or shown timed out
I got help from Gl-inet technician.
Unfortunely can’t found problem reason
And Gl-inet sent new product.
Today I found that reason.
This reason is my opinion
openwrt using rpc that reponse slow then has problem on nginx.
so I checked nginx configuration.
I dont know why keepalive value is 0.
Changed from 0 to 5 then admin panel is working well.
keepalive value effect to perfomence so dont do high number on keepalive value.
I hope this help someone who has problem as like me.
Have a good day.
