Got it fixed today, the entire troubleshooting session is archived in the folder "2026oct12 fix cert nonrenewal after conversion to cloudflared" in my saved files on my hard drive.
While I was at it, I added my rss aggregator's instance to cloudflared's config, so that's working again.
Turns out LLMs know me by an old subdomain I forgot to add to cloudflare's tunnel config. Just added it. See saved chat under filename "Arts Kupietz 404 Issue" in local admin folder.
Today Comcast (boo! hiss!) did some work in my neighborhood and knocked my server offline. I had a long, painful chat session with ChatGPT which ended with me eventually getting set up with cloudflare tunnels instead of using ddclient to update my IP address. The whole chat and terminal session are saved locally in my hard drive in the backups/admin > troubleshooting logs folder in case I ever need to recreate what happened.
I got the error "The number of lookups on your SPF record exceed the allowed limit of 10. This will result in emails failing SPF authentication" in my Cloudflare DNS dashboard.
My spx record for, say, kupietz.com was "v=spf1 include:_spf.myEmailHost.com include:kupietz.com ~all"
Turns out, the problem is, every include can get parsed to be multiple servers. the include:kupietz.com apparently causes a recursive loop, creating more than 10 lookups. I updated it to "v=spf1 ip4:[my server's external IP address] include:_spf.google.com ~all", removing the recursive lookup, and adding my server's IP so it can send me administrative notices.
Also today my ISP changed my IP address unexpectedly... all DNS updated.
For confused first-time visitors and other people still acclimating, here is a description of these little tabs to the left, as well as some other features of the site.
Open "Expert Mode" CLI Navigation - this give you the option to switch your browser's display to an old-fashioned terminal mode where you may browse this site, view pages and images by typing text commands. Just like how we used to browse the web back in 1978!
Open Visual Settings - This gives you controls to customize the visual display of this website to your liking: turn up or down the brightness, contrast, color temperature, hue, saturation, dark mode, and earthquake. Settings are saved per browser tab, so they will be remembered for your whole visit.
Open My Eyes - Have you ever been engrossed in your work, when you suddenly realize someone is staring at your screen, watching everything you do over your shoulder? If not, this simulates the experience.
Open Help - This help popup, silly! You just clicked it! Do you not remember?
New - Draggable elements! Several elements on this website, including these tabs, this popup message, and the "Hire Mike" badge in the lower right, can be dragged around with your mouse, to avoid them blocking content. Positions are remembered per tab, so as you navigate around the site, they will stay in the same place for your whole visit.
Enjoy!
CLI Website Navigation
Are you sure you want to switch to viewing this website in the "expert mode" command-line interface?
This will switch to a terminal emulator, load this page, and allow you to browse this website and view its contents by typing text commands.
Plus there might be, y'know, some fun stuff hidden in there. Just for geeks.
