Python - selenium.common.exceptions.WebDriverException: Message: newSession

Hi,

on a Linux server I have a python script that runs with selenium + geckodriver on firefox. Everything went ok for several months and now I have a mistake:

selenium.common.exceptions.WebDriverException: Message: newSession

Can someone advise you what to do?

Thank you
