I checked the bitcon.conf inside the main folder … what did I do wrong?
Clearly, you don’t mean a folder named main, but you are being a little vague. One possibility is that Bitcoin core isn’t looking for bitcoin.conf in the place you think it is.
On windows it typically looks in %APPDATA%\Bitcoin
On Linux it typically looks in $HOME/.bitcoin
You can specify a particular path to a file using a command option such as
-conf=/path/bitcoin.conf
