Issue with Altium - Unrounted Net

[Shay]

Hello,
I have a weird issue in Altium. It keeps showing me that I have unrounted net, even though it is routed. See the picture for an example:

It is showing un-routed net between the GND th pad and a blind via in pad. The dark yellow is GND layer (it is a 4 layer board).
What could be the issue?
Thanks.

That looks like there are two via's on top of one another, which could cause this.

Although looks like it, there is actually only 1 via.

There are some settings that require every net, including GND to be routed, even if it's on a polygon pour or plane. Its because poly pour can become very narrow. Turn it off or just route it with a track in the poly.

Drag the 'unrouted' via and drop on the big one. It will connect. Then drag it back to where you want it to be.

Is the GND THT pin plated? That could be the issue...

Are you sure there is only 1 via,  that ghost text is a pretty sure sign there are 2 vias on top of each other.
How did you confirm there's only 1?

Select the via and change it's hole and pad size to be very small, like 0.1mm and see if that visually changes what it looks like or not.
If its two via's on top of each other then whichever one you select and change it's size wont make a visual difference because the other is still there.

Do you know which setting it is? routing a track did the job.

Thank you. Seems like the issue is related to some-kind of a rule.

Yes, it is plated.

I removed the via and replaced it, same issue. Double clicking doesn't show any other via, and I tried changing the size and I still can't see any additional via.

Ok, weird issue:
When I route GND pad to GND pad on GND layer, and I repour the GND polygon, it keeps clearence between the track that I routed. Kinda like it does not know that the polygon is actually a GND layer.

I never actually have ground/power planes.
I always have all copper signal layers and simply do a polygon fill over them to make them ground/power only.

Cropped:

Your hint is it's making some clearance, though that wasn't obvious from the first image.

I don't know what use the setting is, honestly, but it's there if you ever need it...

it can be useful to cheat a sense trace into a polygon, like to land it right on a big polygon-connected pad, without having to keep messing with the polygon.  There are arguably better ways of doing that, like splitting the pad in the footprint, with or without net tie, so the trace line can be a separate net.  But's a quick solution, if inconveniently indiscriminate.  Can also be helpful as a reminder that you need to be particular about where a track connects to some polygon routing (for whatever reason) while shoving things around.
