TCP Retransmission & RST

We have a digital application on Android and IOS but when user is trying to access from IOS platform and access the application. During application browsing user is unable to access certain paths of application. And at that time we check on our Palo Alto we get continuous retransmissions on packet captures. And it is happening when accessing application from specific mobile carrier.

Hi @M.Uzair625066 ,

Are you seeing drops on the PA ? Not just in the traffic log but check global counters as well:

Flow basic debugging can help you track the packet flow in more detail and can provide insight on the problem you're experiencing but requires caution as it can impose a heavy load on the CPU:
