Unable to complete Activation of TT Tax Year 2024 Premier

I too, receive the same message as others during 'Activation,' 'You're not connected to the Internet.'  I added TT to my Norton 360 'App permissions,' I rebooted my PC as instructed, reloaded the TT software at the 'Repair~Reinstall' option, but repeatedly receive the same error message.  I purchased the license code at Costco, my fiber internet is working properly at 553.68 Mbps DOWNLOAD and 490.31 Mbps UPLOAD, and I am using 'Malwarebytes Service.'  I have yet to enter my license code -- I haven't yet progressed to that stage.  What is my next step to complete 'Activation?'
