[Labs-l] Connecting to MySQL user database using MySQL Workbench

[Yellowcard]

Hi,

I'd like to connect to one of the MySQL servers where I can create
permanent user databases using MySQL Workbench. According to [1], I
tried to use "tools.dblabs" and "c1.dblabs" as MySQL hostname, but
neither of that works ("Cannot Connect to Database Server"). Using
"enwiki.dblabs" does not work either. However, using "dewiki.dblabs" as
MySQL hostname works fine.

What am I doing wrong?

Thanks in advance,
