This will update your self-signed certificate for Webmin and you will now be able to access the page from Firefox 33 (With the usual browser warning about an untrusted connection).You can check the date and time and time zone in the clock on your computer: (double) click the clock icon on the Windows Taskbar. If you temporarily disabled ssl enable it with ssl=1 in /etc/webmin/nf and restart webmin with "/etc/init.d/webmin restart".
Fill in the form (or leave the defaults) and then click the Create Now button. Just login to the Webmin web UI and select: Webmin -> Webmin Configuration -> SSL Encryption -> Self Signed Certificate.
You can fix this right from Webmin if you use another browser that lets you bypass this type of error or if you temporarily disable SSL in webmin by setting ssl=0 in /etc/webmin/nf and restart webmin with "/etc/init.d/webmin restart". When I looked at the SSL certificate that Webmin was using, I found that it was using a 512 bit key! This must have been the default key size when I installed Webmin a couple of years ago.įirefox 33 no longer supports keys less than 1024 bits (with good reason). I had the same issue with Webmin and firefox 33. It helped me get back the "make security exception" in FF 33.0! If your problem is like mine, on a webmin site, try recreating the certificate from inside webmin. It appears that they will not change this behavior.
