Start WebDriver ERROR

Member for

Hi Philipp,

mysteriously the Start WebDriver-Node causes an Error when its executed.
I've just an simple workflow with WebDriver Factory --> Start WebDriver (URL = http://www.google.de). I used an updated KNIME/Selenium version and the Firefox browser (version 45.0.2).

When I execute the workflow firefox starts (but no site is loaded) and the node Start WebDriver remains in process for round about 30sec (moving blue bar) then the Start WebDriver Node ends in an error:

ERROR Start WebDriver 2:2 Execute failed: Failed to connect to binary FirefoxBinary(C:\Program Files (x86)\Mozilla Firefox\firefox.exe) on port 7055; process output follows:

I tried to reinstall KNIME and Selenium but this doesn't help. Do you may have any suggestions?
Many thanks in advance!
