How to solve this problem

I am trying to run deep learning model in MATLAB 2019a But it shows "alexnet requires the Deep Learning Toolbox Model for AlexNet Network support package. To install this support package, use the Add-On Explorer." When I click Add-On Explorer we get the following message "Check your internet connection and proxy settings in MATLAB Web preferences and then try starting the feature again." Please tell me how to reslove this problem?
