This server has very outdated security installed and only supports TLS 1.0 and SSL3 and neither of these are supported in Firefox 99 (minimum is TLS 1.2).
You can try to download the file using the http:// protocol to see whether that works. You may have to use "Forget About This Site" to clear cached data and prevent Firefox from switching to secure https although Firefox might insist in using https.
You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").
Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.
You can't recover from this 'forget' unless you have a backup of involved files.
If you revisit a 'forgotten' website then data for that website will be saved once again.
