upmpdcli Tidal plugin

2) /var/cache/upmpdcli does not contain a 'cache' folder it seems.
3) I'm not sure what logs you mean

thank you

Hello, I don't want to overlap with @TheOldPresbyope who is helping you.
The directory to look for json files in is in fact not /var/cache/upmpdcli, but /var/cache/upmpdcli/tidal

By logs I mean, the contents of the file /var/log/upmpdcli.log which you can read using 

Code:

cat /var/log/upmpdcli.log

or, via the systemd tools, using

Code:

journalctl -u upmpdcli

That said, please follow @TheOldPresbyope instruction which will most likely solve your issue! :-)
