With our "big" Savegame with 7,7 MB it doesnt work.

I hope you can fix that ... we want play together.

EDIT:
We are only 2 Players.

Thanks for the report,

Hopefully this will be resolved with the multiplayer rewrite

I found a solution for my problem

My router i have a "Enable UDP flood defense" option and without that it works!
So my router think that that will be a attack.
Factorio send more than 2000 packets / sec ... and thats why it will be blocked.
With older Versions of Factorio it worked so i think it send more UDP packets as before.
