Hi John,

Hello @Sweetie_A ,

Most of the cause is .Net Framework missing or version too low. Not sure if this is fresh installation/upgrading? if yes please try to restart Replicate Services, or reboot the whole Replicate Server.

Let us know if it works.

Regards,

John.

Hello @ramu123 ,

We experienced that the windows upgrade reverted the .net framework back to 4.7 which was below our software prerequisites. Are you able to confirm the .NET Framework version? 

thanks,

John.

Hi @ramu123 ,

Welcome and Thank you for reaching out to us on Qlik Community.

The error code “SYS,GENERAL_EXCEPTION,The requested security protocol is not supported” you’re encountering with Qlik Replicate UI is generally caused by a missing or lower version of .NET Framework. Qlik Replicate requires .NET Framework 4.8 or later.

You can check your .NET Framework version by running the following DOS command:

reg query "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\full" /v version

The typical result should be something like:

HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\full
version REG_SZ 4.8.09037

If your .NET Framework version is lower than 4.8, you should update it. All versions of .NET Framework can be found at dotnet.microsoft.com

I hope this helps! Let me know if you have any other queries.
