Hi Harri, > Do I have to upgrade n-m-s to version 1.4.3 for Strongswan 5.6.2?
I don't think so. But the backend was migrated from libnm-glib to libnm which required changes in how the data is passed to NM (see [1] for the commit). Could be that something went wrong there. For instance, it may not actually be necessary to call g_variant_new_unint32() on line 69 in nm_service.c. It might just be enough to pass the value. Could you try the patch in the nm-dns-fix branch.
