BTW, I was not using it purposefully. I think I used it because it was sugg=
ested by TigerVNC viewer itself. The original connect dialogue, I think, ha=
d that address in it. So I used it, and it worked. This is how I remember i=
t. Other than that I NEVER used this wildcard address unless suggested by d=
ocumentation in certain configurations.
With kindest regards,
