So I had what appears to be a small tyre puncture of around 1-2 mm in length on the thread of a road tubeless tyre (Schwalbe Pro One, which is supposed to have some puncture protection, and it seemed to work well for me for the first couple of thousand Ks - 4200kms to be exact).
Old sealant leaked out, some light thread is sticking out of the hole. I have installed a tyre worm, it does not work (does not stick and hold in place, is being pushed out by the pressure, also looks like tyre is bulging out in that spot once there is some pressure. New sealant with a worm in place was not able to seal it - leaked out again.
I had experience with glueless and glue patches with tubes previously - they almost always developped slow (or fast) air leaks despite the vigorous surface preparation and degreasing.
Any good reliable options? Was surprised to see a worm fail. It works just fine on my car. It was a small sized worm though, have not tried a bigger one yet... Just might work. I think that the sealant might prevent worm from working, so I am cleaning and drying the tyre at the moment.
I have retired from this forum, not wasting any more time here.

Glued tube patches have worked reliably, without fail for me on tubes.
Always sand the surface and use the correct glue and no probs.
I have glued the inside of a tubeless tyre with a patch and glue, after a pinch flat down near the rim bed on a gravel tyre.
It has stuck but I haven't used it yet.

Try Dynaplug. It has a metal tip that hooks the plug on the tire. I cut the excess with the supplied knife so that road friction doesn't pull out the plug.

I also wonder if your Pro One is worn too thin after 4200km?

+1 to patch kit with glue, saved my Pro One couple times.

Thanks for the recommendation about dynaplug, I may give it a go.
I was wondering the same, 4200 kms seems like a lot.

Dooes it look worn? The thread did not become visible on top yet... However, the puncture was just outside of the main worn area (but not on the sidewall).

Maybe check the tire wear indicator (TWI).

Sewing (done this a coupla times) works well for sidewalls, but probably not an option for the tread.

I'd try a patch on the inside with the best flexible glue I could find

When you inserted the worm, did you twist the tool around a few times before withdrawing it? This creates a knot in the worm inside the tyre which gives the worm more resistance to being pushed out by air pressure.

DynaPlug and don’t tug on it once it’s pushed in. If you do that, the tip will fall off and roll freely inside your rim…and also increase the risk of the plug being pushed out by air pressure. Contrary to your belief, sealant works in tandem with plugs. Generally after a day or so, Orange Seal sets enough that the DynaPlug is welded in pretty tight.

This still isn’t secure enough at higher pressures. I once tried switching to worms and after an hour, I heard a PSSSSHHH downstairs, discovering spattered sealant all over my floor and wall. I’m glad the puncture was pointed down, otherwise the mess would have been even worse.

I gave up with worms too and I'm now firmly in the Dynaplug camp. For cases where a plug still leaks, weeps or you're just uncomfortable with a plug as a permanent fix, the tubeless patches from Velox and Hutchinson that you apply to the inside of the tyre work well enough. You just have to sand the tyre surface and apply two coats of solution, letting them dry almost fully before applying the patch. These patches are similar to normal patches but don't stretch or bulge under pressure.

Inner liner like a tuffy and inner tube.

Those worms / plugs never worked for me.
