No connectivity to 1.1.1.1 on Tele2 mobile network (NL)

I recently switched my cellular subscription to the Dutch telco Tele2. I noticed I can’t reach 1.1.1.1 on that 4G connection. 1.0.0.1 works though. This is observed on an iPhone, as well as on a desktop that is tethered to the same mobile connection. The desktop is what I used for the manual tests (for output see Pastebin).

The traceroute is interesting, it seems that is already blocked at your own gateway. Is there any way you could remove that block, so it would be more clear where it eventually stops.

This concerns a consumer mobile carrier network, where there’s no hardware of my own involved besides my phone. However I now did the traceroutes from my phone itself (instead of a tethered PC as mentioned above), which might give more useful results.
