Reasons of unable to view or download Tender document Files

The reason for this is that recently Google Chrome (and browsers based on Chromium like Microsoft Edge, Coc Coc, Opera...) has started blocking direct file download links from websites without encrypted connections (such as website: muasamcong.mpi.gov.vn) from secure websites with https (like https://dauthau.asia).
In the Chromium Blog update dated 6/2/2020, which discussed protecting users from insecure downloads in Google Chrome, it stated:

"Today we’re announcing that Chrome will gradually ensure that secure (HTTPS) pages only download secure files. In a series of steps outlined below, we’ll start blocking 'mixed content downloads' (non-HTTPS downloads started on secure pages) to start blocking all insecure subresources on secure pages.”
This means that new versions of Chrome will block downloads accessing from HTTP to HTTPS.
See file download supported versions: https://blog .chromium.org/2020/02/protecting-users-from-insecure.html
