I've seen several threads in the forum where you complain about connection problems between jasperstudio and JasperServer. I can not connect from jasperstudio.5.2.0CE to jasperserver.5.2.0CE all other thred in the forums contain only requests is all unanswered. If no one takes the trouble to answer, I think it wanted to entice you to switch to the paid version? I apologize for my imperfect English. Sincerely
