Vagrant builtin ssh (at `vagrant up`) still problems with key exchange

Hi all,

can anybody advise me on how to draw some attention to this issue?

As far as I can tell I followed the instructions including providing the complete debug output etc.

I cannot work on OPNsense topics, because Vagrant is completely dysfunctional for me.

Short summary: FreeBSD guest, current OpenSSH server from ports, Vagrant up cannot connect into the VM.

Thanks in advance,
