but
curl http://3.r9d.de/.well-known/acme-challenge/k2SWvTsIE1S9xE_Z7W0K3eWxbwXZXexiP1Vawd4g0VM
produces
k2SWvTsIE1S9xE_Z7W0K3eWxbwXZXexiP1Vawd4g0VM.NWID6r6F41f9_k-nsD4_-c_Tg_rup2mu1FV12mbIxV4

I don’t see any requests to that url or the server from LE
no firewalls, ip is correct (91.203.212.170)

what’s going on there?
