Looks like it's impossible to skip the current playing song since the latest update.
Seems the GUI does connect however it doesnt look like it's sending a command to LiquidSoap
2020/03/10 18:51:58 [server:3] New client: 127.0.0.1.
2020/03/10 18:51:58 [server:3] Client 127.0.0.1 disconnected.
However it looks like it's not executed, as soon as I connect via telnet and execute; xxxxxxxxx_local_1.skip the current playing song will be skipped.
Fixed! thanks @SlvrEagle23
I was able to replicate this on our machine, it's able to hit the API, but nothing happens.

@GerritS76 @SC2Mitch This should be fixed as of the latest update.
