Login failed due to wrong credentials though everything's correct

I’m performing the 2nd assignment. Done everything, reset the work items and launched the Dispatcher to add queue items. It gets the correct credential, types it properly, proceeds to the dashboard and… can’t find the dashboard and says that the credentials are wrong. What is it?! I’ve run out of ideas. If I test the workflow separately it works super fine! What’s going on with it?

It even highlights the selector properly. But the Boolean variable turns false. Why?! It works if tested separately… I refuse to understand it.

The problem was the Timeout MS option…
