Added debug exception print when reading config.json

[Nevah5]

I didn't manage to get it to run, recently switched to Linux and still experiencing some issues.

But I need those changes, because I have no clue why I get a config.json error: #129

Oh, there is a pipeline now :)

Can someone merge this? My vpn broke because the ddns is still not capable of reading the config.json
