Unable to download/update Thunderbird without VPN

Hi all, Recently, I wanted to download and install Thunderbird on my Macbook and PC, but I am unable to download the application due to an error.

Thunderbird download links lead me to "https://download-installer.cdn.mozilla.net/pub/..." and "https://ftp.mozilla.org/pub/..." but they both output the following error message:

   502 Server Error
   The server encountered a temporary error and could not complete your request.
   Please try again in 30 seconds.

Out of curiosity, I turned the VPN on and set the location to the US (by the way, I live in Korea). Then I re-attempted to download from the links above, which indeed worked! (as soon as I turn off the VPN, it stops working immediately)

However, I don't think turning on the VPN every install/update is preferable. Is this a known issue? Perhaps a country restriction set-up on the FTP server? If there is a workaround/fix for this issue, any guidance would be greatly appreciated. Thanks.

Hi Toad-Hall, thank you for your reply. I was hoping to use package managers (winget, brew) to install Thunderbird, but I guess my only option would be to manually download and install them through that website.

Thanks for the input!

I will leave this post open for a couple more days before I mark it solved, just in case others might join in the discussion.
