Unable to access on specific mobile app
I would like to raise our incident regarding on our network, something weird.
The main problem with our network is the Wi-Fi Connectivity via TP-Link A6, we encountered no connection, unable to send and received messages on messenger app only with status "Waiting for Network". Kindly see the photo below.
But in other mobile applications there is no problem with the connection via Wi-Fi, able to browse, watching YouTube etc.
Also, we tried to use our mobile phones in other network even in our home and able to send and received the messages on messenger app.
Here is the current netwok device we have.
ISP - Local ISP
TP-Link ER605 - Main Router
TP-Link A6 - Access Point
Please see attached file for router bin
