Oh I have a very specific one for you buckle up haha. So one thing in macOS that gets progressively better and worse over time is actual multi-monitor support. It’s fine but I swear either no one at Apple uses multiple monitors or everyone actually has only cinema displays arranged in a horizontal line haha. I have used OSX/macOS for a long time and it was much worse for a long time but had gotten pretty workable then BAM around Tahoe or so arrangement is buried in some menu now and I’m not sure the function of the row of displays actually is now? Anyway, it’s mostly great, this is the one thing that apparently turns into a rant haha! Okay two things, bring back eGPUs on Apple Silicon :D








So I am pretty sure that error is happening because certbot can’t retrieve the certificate which is coming from that API no matter what type of challenge you are using (this is what ACME is).
Now when you say you are blocking inbound traffic, have you made an exception for established outbound session return traffic? If not then you your inbound rule will block all traffic because without that exception the explicit deny will typically override any session/stateful based rules your firewall might have by default (this applies to most firewall vendors I have run into).
That said, I’m not sure what your goal is but blocking outbound traffic to those ASN might be more effective for you anyway because your firewall should already be dropping any inbound traffic that isn’t otherwise allowed so I’m not sure blocking inbound traffic really gains you anything but I’m just guessing. Hope that all makes sense!
