Hey, currently getting this issue when I try to connect to my database...

Initialising it with this: sql = new MySQL("192.168.1.XXX", "3306", "XXX", "XXX", "XXX", "");

Hey mate, communications link is usually due to being unable to connect to the database, are you sure it’s accessible? / running

[BenHall-1]

Yeah seems to be, I can access it from MySQL workbench on the same PC... hmm I'll try a few things and see if it is user error

[Huskehhh]

How'd you go mate?

[BenHall-1]

The credentials are correct as I can use them on SQL Workbench... not sure what else to try tbf

[BenHall-1]

Nvm I fixed it, I forgot that I was running the MySQL server without an SSL Cert so I needed to use &useSSL=false
