DNS resolver exiting when loading pfblocker 25.03.b.20250409.2208

Hmm, does it only happen in Safari? Does it happen everytime you refresh the page? Any page?
Still trying to get more data points here. Seems like it must be something very specific.

Only happens on Safari (I only use Safari and Brave).
Seems like a common issue when I Googled it. This example is a bit dated though:
**If a user from Safari Web browser (Apple devices) visit your site. The browser tries to fetch the site icon if it is not defined in <head> in the following order:
apple-touch-icon-57x57-precomposed.png
apple-touch-icon-57x57.png
apple-touch-icon-precomposed.png
apple-touch-icon.pngTo resolve this issue either define an icon for safari web browsers or apple devices. Add something like this to head section of your site:
<link rel="apple-touch-icon" href="/custom_icon.png"/>
If you want to keep <head> clean then upload the icon to root dir of your site with proper name.You can find more details on iOS developer library.**
It also came up as a pfSense issue from back in the day:
https://redmine.pfsense.org/issues/6727

Right. Which is weird because it is defined in head.

@stephenw10
It only seems to happen when using macOS Touch ID to log into the pfSense GUI. More details in the Apple dev library, apparently.️ -
Aha, that's fun...

OK try the patch on the redmine if you can: https://redmine.pfsense.org/issues/6727#note-2

Patched and did a quick log-out and log back in and all was well. I'll look at it in more detail tomorrow.

Thanks!

Fully tested - patch 6855d0f643a33 is confirmed to work with 25.03.b.20250610.1659.
No remaining issues or observations - looks like a fix.
As an aside the 25.03 update is looking really good. Rock-solid stability, nice new features and a massive performance upgrade for PPPoE WANs.
I know our role is to pick holes in it but this is one of the best updates in recent years.

Awesome! Thanks for testing.

I've no idea why this error returned this morning as nothing had changed:

Hmm, weird. Some other page that doesn't have meta data in the header? What were you looking at that triggered it?
-
@stephenw10
The blue pfSense login page just after refreshing the pfSense red screen (the timed-out / credentials / whatever thing).️ -
Ah, the CSRF token timeout? Maybe it tries to pull icons from there...
-
@stephenw10
Yes, that's the one my brain was hiding from me - CSRF token!️ -

Over 72 hrs since my last boot and zero issues with the false interface errors. Packages are happy and DNS resolver has a healthy cache again. Looking like a fix.

The fix for VIPs on PPPoE went into that beta. But I'm not sure how that would affect LAN...
A month later and unfortunately the erroneous 'hotplug' events have returned with 25.07.b.20250707.2346.
The only other change is that I'm not running the RA patch as that should be in the current beta.

Hmm, damn. I assume that repeats a lot.
I doubt the RC will be different TBH.

I have the RC up and running now so will monitor. The patch for the Apple png files didn't make the build (as you suspected) and the previous diff patch no longer works with the latest changes.

I can resolve names using DNS lookup on the pfSense, so Unbound is somehow working
I was reading through this thread...pfSense creates a route for a custom Monitor IP used for gateway monitoring so if that is the same as your DNS server, that IP will have a route.

@SteveITS
Speaking of today, I am using the new snapshot—the pfSense release candidate. A lot has changed since this thread was created. At the moment, there are no issues with the resolver for me. In fact, most of the problems I had were likely caused by an incompatible IPv6 configuration. According to the documentation, it wasn’t supposed to work properly anyway, so I reconfigured it to be more compatible. Also, there have been new patches and other improvements as well.
