Quectel-cm is not setting up data session after a disconnection and once service is available

At the beginning of the test, we establish data session with a APN using the quectel CM modem on LTE network. During the test, we run some attack scenario so quectel-CM gets disconnected . Once the attackl is tuned off and network is available , quectel-CM is not reestablishing the data session . I don’t see any “requectSetupDataCall WdsConnection message” . I tried to trigger the data session by running quectel-CM again with the APN name ( ./quectel-cm -s wirelessone.com) but that didn’t work
How can I trigger requestSetupDataCall WdsConnectionIPv4Handle so wwan0 interface is up and obtains an IP

When data session gets setup:
[06-11_08:07:14:808] requestQueryDataCall IPv4ConnectionStatus: DISCONNECTED
[06-11_08:07:14:809] ifconfig wwan0 0.0.0.0

data session is down after the attack

I also ran another simple test where there was no network connectivity(LTE) at the beginning. I tried to setup a data session with a APN ( quectel-cm -s wirelessone.com) . Obviously, no connection will setup as there is no network connectivity. I stop that test and bring up the LTE network and try to setup data session using quectel-CM with the APN and it fails to setup session . If I reboot the modem and run the session setup while network is available, data session will setup

It looks like if there is a failed attemp to setup data session , modem can’t recover from it even after network is available and even if I trigger the session setup with APN . I am using below quectel ConnectionManager. Is it possible if there is any issue on below modem version or I am doing something wrong?
