eDiscovery Download Manager Error - Can't Download Results

Question

Good day.
SharePoint 2019 environment with eDiscovery site running - Searching and Results working as expected. However attempts to download the results or reports fail. The dialog box to browse and select where to save the results is shown but it then closes out without the ability to actually click browse and save the file. The error below is in the application log each time this fails. I have search but cannot find any resolution. I'm logged into my laptop using the same AD account used to login to the eDiscovery site (I have Membership rights in the eDiscovery site). Suggestions? Anyone see this before? Thank you.

Hi all,
Wanted to provide an update on the fix for this. The issue is that the eDownload Discovery Manager program was attempting to communicate with the server over TLS 1.0 and this was resetting the connection (found this after WireShark trace analysis and comparing to the trace from the server where it was working). The following registry values had to be put on the workstation to get it to run successfully. Regards.

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft.NETFramework\v2.0.50727]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v2.0.50727]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001

Please check as following to narrow down this issue:

1. What browser are you using to export the results? Use IE11 to perform this action and see if it works.
2. Do you see the same error if you click "Download Report" button on Export Download page?
3. Can you reproduce this issue if you switch to another machine or use another account?

It seems to be error related to the eDiscovery Download Manager itself. Please check if there is any other error message while executing the eDiscovery Download Manager via Event Viewer or ULS logs, so that we can further look into this issue.

Slight breakthrough - I did get it to work when loading the eDiscovery site in a browser on servers in the farm. However, it will not work on workstations. Wondering if it might be firewall/communications issue so a request has been made for extracts of logs to determine if any dropped traffic is the root cause.
