Can connect to MySQL server within unity, but not in standalone build

I am able to read and write from my sql server when I am still inside unity, but when I build the game it no longer does anything sql related. I already tried copying all of the dll’s into the assets folder, but that did not change anything. Is there something else that I have to do in order to get this to work?

What have you already done to debug the issue? Have you checked the output log? What’s your used scripting backend and .NET version? The DLLs should be placed in the plugins folder inside the Assets folder. Which library / connector do you actually use?
