Getting the below error when trying to make calls to a mechanize browser instance.

Using mechanize v0.4.3

Below causes the issue:

br = mechanize.Browser()
br.set_handle_robots(False)
br.open('https://online.asb.co.nz/auth/')
br.select_form(name="login") # Error occurs here, also happens with br.title() etc as well

Try downgrading openssl to 1.1.1d.

We are also having this issue in our project and I am currently investigating.

Thanks, downgrading to 1.1.1d did the trick :) Will stop that package from upgrading for now till the issue is resolved.

@ZephireNZ and @jacobtomlinson - sorry you're having problems. Unfortunately this project is the Ruby library named mechanize and not the Python library.
