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 did lot of searching but not find any solution. Kindly suggest the way. It is working fine inside server , but not working from user's machines. When I check into event logs , see these two errors and mentioned in the snapshot. Unchecked and checked .NET features from windows but still no luck.

    Hi @Rahim Molvani ,

    Thank you for posting in this community.

    The same problem has been reported before and a solution has been provided.

    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.

    [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 "SchUseStrongCrypto"=dword:00000001
