I have got the same warning when running the plutus-playground-server locally. You should be able to use the Playground despite there is a warning. I think this is only needed if the playground will be deployed somewhere and you want to offer a Login via Github Open Auth flow.

I actually already asked about the GitHub ID in another question, but am looking for guidance on the JWT_SIGNATURE setting indicated in t he last warning line before Interpreter ready statement.
Or, am I missing something more obvious than that, like the (Nothing,Webserver{...}) statement in line 1?
Thank you for any help in advance!!

As Marco writes, this is fine. The `(Nothing,Webserver { ... })` line is just informative. The warnings are also of informative value only and do not constitute an actual error.
