extreme long time when requesting data from PNA

I have been using Matlab instrument control toolbox to talk to my N5221B PNA and everything worked perfectly until a recent system reboot.  After the system reboot, when I send the read data command CALC:DATA:SNP:PORTs?, it tooks almost two minutes to return the results of a 4-port measurement (I checked the SCPI monitor after I sent in the command).  The following command in my script is a bin block read. If I don't wait long enough, it surely leads to an error. I haven't changed any measurement settings, the sweep range and data points keep the same. I am wondering what could be the possible reason causing this extreme delay in returning the measurement data. Any advice will be appreciated. Thanks
