Anonymous users being prompted for credentials when accessing documents with Edge

[Jronash]

We have an on-prem SharePoint instance running a public site.  There are document libraries on the site with anonymous access enabled.

Recently, we've noticed that if a user follows the link to a document in that library using Edge, the document will open in Word (assuming they have Word installed), but will ask for a username and password.

If they use any other browser, the document just downloads like normal.

Is there anything we can do on our end to stop this behavior?

This is an issue with TLS 1.2 settings in the ie/ edge browser. You need try disabling tls1.2 nad check

Thanks Aravinda, but since we don't have control over our site visitor's web browsers, I don't think this solution would work for us.

We were able to solve the problem using URL re-writes. We found that if you tried to download the file using this URL, it would work properly:
https://www.sitename.com/_layouts/15/download.aspx?SourceUrl=path/to/document.docx

So we have a rule that catches any document download attempts and redirects them to that path instead.
