We have two 3300 MXE II's at SW level 4.2. We are trying to bring them up to 7.2. We have internet connectivity. We can reach out to the AMC to verify. When we use the Software Installer Tool all is well until it brings up the App Record License form. When we select "Retrieve License" the Internet Connection drops, ex can't get google. Is this Cisco switch/firewall issue or something else? Two different laptops. The two controllers are clustered. The secondary serves only as a backup. And is the one we are trying to do 1st.
