      Hi,

       

      I create for my process a task form by guvnor/ designer. When I run my process using the local port http://localhost:8080/jbpm-console/ everything works fine:

      But when I try to run the process on my external test server I got a strange behaviour:

      • I get asked for credentials again
      • When I enter them, I receive an error

      I read this posts: https://community.jboss.org/message/643297#643297 but I don't have whitespaces in the task name.

       

      Any suggestions?

       

      Thank you,
