Hello,

I am trying to use rostest in my node and it works well on my laptop. But when I try to run it on NUC 8 for the first time, it fails due to exceeding the time allocated for test. The second time and so everything works fine. The only difference between the first run and others is the error message on first run:

[ERROR] [1630059460.157849168]: [setParam] Failed to contact master at [robot-NUC8i7BEH:41635]. Retrying...

As far as I know, rostest doesn't require roscore to run, but even if I run rosocre it doesn't help.

Do you have any ideas about this strange behavior? Thanks
