Hello,
it seems that there is something wrong with the DNSSEC status.
The connection test shows an error at the DNSSEC test.
But if I check th result at https://dnssec.vs.uni-due.de/ all is fine:
If I disable DNSSEC at turris, the result at uni-due.de is “No DNSSEC”. So it seems that this worked as expected.
Version: Turris 4.0.3 on Turris MOX, branch hbs
