Proteus xml_rpc connection problem 7.8

Support Developer
1

Hi folks,
I need your help. I am not able to connect to a newly created 7.8 database using proteus. The same setup works for 7.6. As you ca see database exists localhost in running on 8078. You have to trust me that admin is correct and this very complicated password too. What am I doing wrong.

this way works, but xml_rpc seems to have a problem.

Is there any error message on the trytond side ?

You’re missing the end of the traceback (which is the most interesting part :smiley:).
