One more thing.
I’ve started from scratch, deleted everything.
Then, I try to reach with a curl the external service, and I things work (I get 403, “as expected” - in this phase).
Then, I simply install the serviceentry and the same curl starts to return curl: (35) error:1400410B:SSL routines:CONNECT_CR_SRVR_HELLO:wrong version number.
I’ve googled (and Googled…) and I find many issues similar to this one, apparently with no clear answers.
I guess this should be fixed first, then I can move forward and think to the rest.
Thoughts?
