JACK2 error: DBus exception: org.jackaudio.Error.Generic:

Question

I try to follow https://wiki.archlinux.org/index.php/JA … ection_Kit
to work with JACK2 D-Bus but I get:
$ jack_control start
--- start
DBus exception: org.jackaudio.Error.Generic: Failed to open server
I have consulted this thread without results.
When I open qjackctl and attempt to start the server I get:
01:56:11.937 Patchbay deactivated.
01:56:11.943 Statistics reset.
01:56:11.945 ALSA connection change.
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
01:56:11.954 ALSA connection graph change.
01:56:20.676 JACK is starting...
01:56:20.676 jackd -dalsa -dhw:0 -r48000 -p1024 -n2
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
01:56:20.680 Could not start JACK. Sorry.
01:56:22.012 JACK was stopped
Any ideas?

Answer 1

Got the errors.
1) DB_STATUS.. error was coming since the lookup I gave there was not actually created in the database due to a refresh I did while creating it effectively deleting all the entered data.
2) The error in logs was coming due to wrong input of the GTC database provider during the creation of IT Resource.
