cannot connect to chrome - some of the time

[LazerJesus]

about 4 of 5 times running ad_clicker i get the attached error.
1/5 no problem and it does what its supposed to.
I run poetry run python ad_clicker.py -q "dogfood" -t 5 --headless
its locally installed using git clone and up to date, running on Mac M2.

I don't recommend headless mode since it increases the chance of blocking. Try without headless. Also, it can be a Mac related issue.

[LazerJesus]

i dont think its a blocking question. according to the error message the script can connect to chrome.
how might this be mac related?

[coskundeniz]

I said it may be Mac related because I am a Linux user and don't see this error. Also, most premium buyers are Windows users and didn't see it on their system either. You can retry by deleting downloaded chromedriver and without headless. Thanks.
