Docker network br0 not found

[knex666]

Dear Unraid friends,

 

after I changed IPV6 from manual to automatic and back to set a new IPV6 prefix I have some trouble with the docker daemon. the docker network bridge br0 is not found.

 

This solution doesnt work: 

This works but only manual so its no solution:

Another problem is that even if I add the bridge manualy I have no longer IPV6 support for docker. How do I enable that?

Here are some Log files in hope you have an idea what I am missing.

Thank you very much for your help!

br0 is not created because there is some conflict in the network settings.

Can you post a screenshot of your network settings.

[knex666]

Thanks!

 

Hope that will make you find the mistake.

Your IPv6 address is wrongly set as a single host address (/128), it has to be defined as a subnet range (usually /64, check also your router settings).

Yay after setting it so some static IPV6 with 64 prefix everythink works fine again, THANKS!!!
