Dropbox thinks my PC is offline

[Lyralina]

Dropbox installer fails, saying "The installer could not connect to the Internet. Ensure that your computer is connected to the Internet and your firewall allows DropboxUpdate.exe to connect then try again".

But there's internet because I'm able to browse the internet just fine. I have Windows 11 Home 64bit. 

So I tried installing using the Dropbox offline installer. I was able to install Dropbox, but when I try to start it, it still says "No internet connection. Your computer is currently offline. Please check your network settings."

Again, there is internet because I'm able to write this. Any ideas?

I only have Windows Defender now, but I used to have free trial of Mcafee that came with the computer but uninstalled it. I think it might be related?

Hey @bburbank, let's jump right into this! 

Is the desktop app's icon showing up in your system tray at all?

Also, do you get any specific error messages? If so, feel free to send me a screenshot of the message you get, in order for me to have a visual too.

Let me know more, and we'll take it from there!
