CWMP ConnectionRequest Failed
we have a few TD-W9960 v1 devices that connected to ACS service .
in most scenarios of ACS the server will make a ConnectionRequest to device and device will initiate a connection to ACS Server with "4 CONNECTION REQUEST" event .
we have tried a lot to trigger a ConnectionRequest for this devices but failed . the connectionRequest will responded with HTTP 200 code and it's ok but nothing came from device . this happening to all W9960 devices we have not one or two device .
Did you have a problem like this ? how solve it ? is there any special way to make connectionRequest to this device ?
