Unable to connect Server after update (Direwolf 1.0.4)

I can start my server just fine and it runs through without crashes, but it appears offline if I want to connect. I´ve checked the logs and found this:

I´ve updated my server doing the following:
-complete backup of all old files
-deleted all old files
-got the new server pack
-accepted the eula and started the new server pack
-once it finished generating spawn area, I´ve turned it off
-copied over my ops, whitelist, server.properties and world into the new folder
-started the server

My fml-server-log doesn´t show any errors. Also I´m using a host.

Problem solved. Had nothing to do with this. Some blocks were removed in the most recent update so I had to approve of deleting them. Thread can be closed.
