Tonight, unexpectedly my Mac lost its connection to the internet. My Mac has an installed HTTPS certificate from my eBlocker and HTTPS is activated. Obviously there is something happend with the HTTPS configuration in the eBlocker. Because both of my gadgets that are running a HTTPS certificate are unable to connect the internet. But when I on this gadgets discable HTTPS or eBlocker at all, both connect to the internet. The diagnosis tools from my eBlocker doesn’t show any failures. What should I do in order to determine the cause of the malfunction of HTTPS?
With HTTPS disabled:
With HTTPS enabled, after restarting the Mac:
@facebita It reads clearly: The eBlocker has no Internet connection.
I would suggest to
- Reboot eBlocker (Settings>System>Reboot)
- Check System>Doctor & take a screenshot & share
If you still have trouble I'd
- Reboot router
- Check for parental controls set in router that maybe block Internet
- Double check network LEDs are flickering - maybe change cable
- Check the DNS servers are all answering fast and reliably:
THX!
- Reboot eBlocker (Settings>System>Reboot)
Thanks. Obviously already the reboot took the trick.
One additional question at this point: Why did it not make trouble that, when restarting the eBlocker, at least for a moment no DHCP server is available in the network?
- Check System>Doctor & take a screenshot & share
There is nothing unusual to see. At Beginners view all buttons are green and checked. At Experts view all buttons are green too, the both first buttons advice to enable Banner filter and Radar filter.
- Check the DNS servers are all answering fast and reliably:
That's interesting. At my eBlocker the DNS server at 9.9.9.9 ist marked as being unavailable. The server at 1.1.1.1 is fast and high, as shown at your screenshot too.
Just to make the issue more clear: Your Internet connection was down. Nothing to do with eBlocker or HTTPS, but probably just a temporary issue at your provider.
Why did it not make trouble that, when restarting the eBlocker, at least for a moment no DHCP server is available in the network?
The client caches all received DHCP configuration until the end of the lease time is reached. See here for background. There is no need to make any changes! This is just for your IT background.
At my eBlocker the DNS server at 9.9.9.9 ist marked as being unavailable.
Then I'd suggest to remove the DNS entry, in case it's still unavailable after your Internet connection is up again.
THX!
