Work on browser steps, but fail in real use

[Churator]

I complete browser steps flow, but when I run the actual flow I get failure on some reasons:
Site 1: Exception: Page.goto: net::ERR_HTTP_RESPONSE_CODE_FAILURE at https://booking.slope.it/cd1c142f-7791-4881-947c-74f5166de463 Call log: - navigating to "https://booking.slope.it/cd1c142f-7791-4881-947c-74f5166de463", waiting until "load"
Site 2: Browser step at position 7 could not run, check the watch, add a delay if necessary, view Browser Steps to see screenshot at that step. Page.wait_for_timeout: Target page, context or browser has been closed

Even visual filter show the end result I'm expecting
