Hi Wolfgang. Thank you for asking the question here again for the benefit of others. You are right, Google has removed the described link to the certificate view. It is now available through the developer console, which you can bring up by pressing F12 (on most systems anyway) and then switching to the Security tab. Click on "View Certificate" and you are good to go.
Here is the place where I found the answer to this:https://tech.slashdot.org/story/17/01/29/1820232/heres-where-google-hid-chromes-ssl-certificate-information
If you like to ditch chrome for this task in the first place you can follow these instructions here:https://askubuntu.com/questions/156620/how-to-verify-the-ssl-fingerprint-by-command-line-wget-curl
P.S.: if this answers your question please select this answer as "best answer"
