@marcelobartsch thanks so much for taking the time to track this down and open this PR; sorry, for all the hassle! Also, great spot on the ClientCertFile 😄. I'll cut a new release with these fixes ASAP.

@marcelobartsch, now back in front of a PC and on closer examination, opts.Context is already being set here (only if use_local_config = true). So, possibly the only underlying issue was the client cert. I've dropped the change you made to set opts.Context (which also missed fetching the value from the relevant env var) from this PR. Would you be able to test again at some point and confirm if just the fix for ClientCertFile works for you?

PR needs further discussion. Should not be merged at this point.

the change for clientCert file works!! and you were totally right on the context stuff, I had a extra env variable causing havoc in my setup.

Thanks you so much for the help on fixing this!!!
