My most frequent issue is that links created through an email service provider like ConvertKit will get blocked by PiHole.
I’m a small business owner and so I get a lot of other people’s newsletters, on purpose. I like seeing what mentors and colleagues are doing with their businesses. But a link to their website, a blog post, anything really will almost always be blocked by PiHole if it’s sent via an ESP. This kind of “tracking” (email clicks from a small biz I know and trust) is something I am totally fine with.
It’s easy to disable for 1 minute to click through, but sometimes I forget that the PiHole is active and I can’t figure out why the links aren’t working.
I don’t manage our PiHole, so easier said than done. I’m the non tech spouse (although not clicking ads or on TikTok all day, lol) but I can’t bug my spouse in the middle of the day to whitelist something for me. I can easily disable it myself and it takes 10 seconds. I could learn how to whitelist, but TBH I have enough tech to keep up with for the business already.
