Hello

we had the same problem yesterday …

i just went to switch settings / Layer 2 / RSTP / settings / enable port fast status
no more problems

We are using Alcatel switches

hope it helps

best regards , J

i was stuck at the same screen for days before i found the solution

fog server ip 172.16.1.105
fog hostname debianfog
fog fqdn debianfog.debianfog.local

juts edit your hosts file … nano /etc/hosts and add
172.16.1.105 debianfog.debianfog.local debianfog

Now mullticast starts without any problem
