Hello Jeffery,

If this is the 2024.1, See Unable to open the Database Utility or connect remote clients - Network 2024.1 for the DLL file which should help.

~Delray

We tried the DLL and it didn't work

Then go through the troubleshooting process since something was missed: How to troubleshoot System Database Connection Error

The thing is it always work on reinstall and error out the next day. So configuration and network should be fine, what else can help me troubleshoot?

Without information, the details of the configuration, I am useless. I need details to me constructive.

I might suggest looking at you firewall policies and/or Anti-viral programs, if it is working after an uninstall/install then stops, that suggests something is changing. If it is not in the SFA configuration as laid out in the articles, then it has to be in the environment.
