A non-protected site requiring https is weird.

The FAQ states https is supported. Confirmed in the log:
0:47:25 Info:  engine: transfer-status: link error (404, 'Not Found'):
<https://www2.psdb.org.br/robots.txt>
10:47:26 Info:  No robots.txt rules at <https://www2.psdb.org.br>
10:47:26 Debug:  Wait get: <https://www2.psdb.org.br/home/index.php>
10:47:26 Warning:  Retry after error -4 (Interrupted transfer) at link
<https://www2.psdb.org.br/home/index.php> (from primary/primary)

No robots.txt, https matter, timeouts, browser ID, http 1.0 don't help. I have
no clue.
