That resolved the issue. Thanks for the hint.

Try upgrading to the latest network package. There's a bug prior to
version 2.4.1.0 where 'connect' blocks other threads from running,

Somewhat unrelated, but if your program needs to run for long periods
of time (e.g. a server), you're in for a nasty surprise: GHC
currently
doesn't support interrupting network I/O on Windows. After about a
thousand hung connections, the program will run out of address space
and hang. A partial workaround is to use socket timeouts; see
setHandleTimeouts in the network-socket-options package.
