Is microfocus having a problem again on certain platforms?
I don’t know. But today I did get a login prompt (instead of being already logged in) more often than usual.
If your browser displays a HTTPS-//TLS-related error, check the date and time on your laptop.
For example, http://time.is/ displays the exact time, and how much your laptop’s time differs from it. Adjust your system time and try again.
(Context: I’ve had hardware that kept »forgetting« the time due to broken or old real-time clocks and/or empty batteries. Since TLS-based handshakes seem to require reasonably correct timekeeping, I found incorrect system time to be the culprit of failed secure connections more than once.)
