INET_E_DOWNLOAD_FAILURE error Edge browser in IE mode

Question

I have been unable to get IE mode working on a server and have tried all fixes listed in the two articles below, to no avail. I am a corporate customer and attempted to open a ticket with Microsoft but there doesn't appear to be support for Edge. Note that, outside of IE mode, Edge appears to be working fine.

Has anyone else run into this and know of anything else that I can try? I should note that there is another server in the same environment, same server build, getting the same policies, with the same user account, that does not have this issue.

Note that I also tried reinstalling Edge and deleting the user profile.

Hi @SP_Steve ,

It looks like a TLS-related problem. Please try setting the following reg keys:

1. In Registry Editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL
2. If you do not have AllowInsecureRenegoServers created, create a new DWORD value named AllowInsecureRenegoServers
3. Set AllowInsecureRenegoServers value to 1
4. Create another DWORD value named AllowInsecureRenegoClients and set it to 1
5. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings
6. Create another DWORD value named EnableInsecureTlsFallback and set it to 1
7. Restart your computer

This was due to traffic to the target site being blocked by a firewall rule in Azure (servers also run in Azure). The one server was allowed but not the other. Terrible error message, but it's IE mode so I can't expect much.
