rsync: [Receiver] failed to connect to feed.community.greenbone.net (2a0e:6b40:20:106:20c:29ff:fe67:cbb5): Network is unreachable (101)

Hello robin,

i had a running installation, made the update to 21.04 and checked the installation.

Allthough everything seems to be fine - i can not update the feeds.

Yesterday i was able to update NVT with “sudo gvm-feed-update”.

All other feeds failed.

Today i get “Connection refused” on all feeds. (Needed to mask the hosts in the post …)

I think there’s a problem with the servers or maybe they want to get all those “free users” out of the system.

I can not imagine that paying users have the same issue.

As there’s many posts abbout this but not really a solution - i do not have a lot of hope this will be fixed.

Replying to my own post …

I found some hints regarding IPV4 NAT issues.
So i configured my system to be able to use IPV6 also.
This seems to make a difference as now there’s some “action”:

└─$ sudo gvm-feed-update
[sudo] password for xxxxxxx:

currenty the system is working. I will need to wait for the result …
