@DevOps-Martins Out of curiosity, did Geckodriver v0.29.1 work for you and Chromedriver 2.44?
I can add those extra lines to the standard Dockerfile (and remove RUN seleniumbase install chromedriver and
RUN seleniumbase install geckodriver) after making the version updates, but it seems those lines are specific to your environment possibly? Did the Dockerfile work for you in the default environment?

@DevOps-Martins Also, which line of SeleniumBase code did you receive the SSLCertVerificationError on? (Maybe that part can be fixed easily.)

@mdmintz The most recent versions of the drivers did work. And the Dockerfile does work as expected in a "home lab" environment. My issue is I'm behind a lot of security layers at my job. I would say you can keep the original dockerfile and just add the manual way of doing it as a comment. Below is the error log (This is from within the docker container):

@DevOps-Martins I think I see the issue. It looks like the Python requests.get() on https://chromedriver.storage.googleapis.com/LATEST_RELEASE returns the SSLCertVerificationError from your server, but they also have an http version of the same URL: http://chromedriver.storage.googleapis.com/LATEST_RELEASE
If you're able to reproduce the issue on the https url, but not on the http version, then the fix would be rather easy for me to do. I could ship that in the next SeleniumBase release if you can verify that.
