When I tried accessing the mange workflow inventory page for a sub site, the SP return sorry something went wrong screen.
I troubleshoot the log files with the correlation id, but couldn't find the reason for this.
Here is the error log details: Application error when access /_layouts/15/NintexWorkflow/WorkflowGallery.aspx, Error=The wait operation timed out
|Error establishing database connection. SQL Error: -2.: System.Data.SqlClient.SqlException (0x80131904): Timeout expired.

I checked database setup, and no upgrade option is available, so I'm assuming my db's are up to date. And when I see the manage database mappings, the DB which was for my site where I'm seeing the error: was not mapped to any specific nintex db, it is showing any available workflow content database option from dropdown.
But for a while back, I was able to access the manage workflows page without any issues. But I observed this behavior on a site, and later today I found it on another site from different site collection. I'm afraid that it may happen with other sites too. Any help would be much appreciated.
