Greetings,
I've tried to isolate the problem really hard but without success, it goes
rogue totally unexpected. All I was able to get is that it happens only at
the proxy creation but other circumstances are unknown. I ended up moving
endpoints configuration to the code, we'll see how it goes now.
Thanks for your help!
