Chrome has become very strict regarding certificates. There is no longer a straightforward way to access a page with an invalid certificate. Instead, you will receive a net::ERR_CERT_AUTHORITY_INVALID error message. Fortunately, there is a workaround.
To utilize this workaround, you need to launch Chrome with a specific command-line parameter. On Windows, the command is:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --ignore-certificate-errors
On macOS, the command is:
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --ignore-certificate-errors --ignore-urlfetcher-cert-requests &> /dev/null
By launching Chrome with these commands, you can open pages with invalid certificates.
