Connecting titra and wekan is extremely difficult task.

I would say almost impossible. I have spend about 12 hours looking exhaustively into Cors and Nginx configuration, certificates. etc etc. Playing cat-mouse game sort of speak. Trying to figure out how to go around the correct Nginx config for Wekan and then for Titra. but most importantly doing cors just between Titra.test and Wekan.test. Never works. Impossible. I have read all documentation. So, if there is any secret that I need learn. I would really appreciate it now. Because, right now, I sure. Is not possible.
