desktop_navigation_provisional_load_failed when downloading a file sent in chat

Regular Visitor


Since a few days I cannot download any file sent to me via Teams chat. I press the ... next to the file, choose Download but nothing happens. There is no Teams notification and there is no received file in my Downloads directory.

I debugged this problem by triggering the download a few times in a row with 10 seconds pause between. Then I pressed ctrl shift alt 1 and Teams saved the logs to Downloads\MSTeams Diagnostics Log<date>\.

I looked at desktop\logs.txt file and then matched the time I hit the download button against any log entries at that time.

It turns out each time I pressed download there was a desktop_navigation_provisional_load_failed error (I replaced the ", " by ",\n" for easy reading)

Can you help me determine the cause of this problem?
