Yes, I was aware that if you turn off https, Chrome will just connect. Downside is, there is then no encryption during the login, so it violates our security policy.
I’m using the 2.5.4 firmware on the B24, which I have only installed a couple of months ago (our first two Mimosa).
I’m using the latest Chrome (95.0.4638.54), and this started after I updated Chrome (also something our security policy decrees, so I can’t just go back to an older version).
Now when Chrome sees a self signed SSL cert, you still get to select Advanced, but Chrome then just prints a warning. There is no longer an I accept the risk button. That’s where blindly typing “thisisunsafe” acts like the I accept button.
For private networks, we have been using self signed certs, and adding the Cert to the support staff’s browsers. For our publicly accessible kit, we have been using Quovadis Certs, but are moving to letsencrypt.
