Make sure you have up-to-date DNS, if not flush it, the IP is changed
once in a while to there maybe temporary issues.

I don't know how apache or other web servers handle standard error of the
applications they start, most of them just ignore it so I would not
relay on this.

Logging is done using BOOSTER_ERROR like family of macros:
See: http://art-blog.no-ip.info/cppcms_ref_v0_99/log_8h-source.html
Basically you do
BOOSTER_WARNING("myapp") << "Failed to do something for " << foo;
This allows you to filter messages by warning levels and specific
application parts that should be traced.
See: cppcms::log namespace for details (in Doxygen reference)

Likely nowhere as most web servers ignore standard error of the application
and redirect it to /dev/null
