im using the gui version of the hydra bruteforcer

my Problem

hydra tells my its connected to the host and tested my list of passwords over a defined user but
i had for a test a known user selected and the password is in the list....

Hydra finished the session with no success ....

The Forum was for the test attacked has no capcha or another technics.

the settings was http+get

i think is my problem is thats hydra cant locate the logon site for the Forum

when i give hydra the detailed address for the Forum with /index.php
tells me via verbose failed connected to host.

but when i give only the adress of the host Example Web Page his will connecting to the host and "works" with no hits by known logon : pass combinations.

can any help me with this ?
