My go to troubleshooting method for open source tools I use is to just read the code to figure out what it’s doing (if I can’t quickly figure it out from the documentation). I’ve certainly learnt a lot from doing it, and I’ve even written patches for tools written in all sorts of languages that I’d never used before. The first time I ever wrote Rust and Go code, I was patching bugs in open source projects that I needed to have fixed.
