Hi @i2cute
I don’t use Druid, but since the error is “no protocol”, I would guess it’s because you entered as host instead of ?

Thanks so much. http is required for the connection, never thought about it.

Really appreciate it :smiley: :+1::+1:

Sorry, 1 more question, how to pass in druid username password? :blush:

@i2cute I don’t think you pass those - I think it asks for username/password on save and then a token is stored, but I have no idea how Druid works.
