Jo so we have a minecraft hamachi server with its own modpack and whenever I connect with the server at hamachi exclamation point and I'll immediately kicked back with the above error. The host can't ping me at hamachi, then have the firewall disabled after that it went, with the server I could not connect yet dennnoch.
There are 2 possibilities:
The connection does not come off or it is canceled immediately.
The first one you test with ping and tracert etc.
In the second case, it can help if you drastically reduce the speed with which you are allowed to communicate. In ancient times it was that a "computer chatterbox could talk the other down". Then the connection broke off because of "misunderstanding".
Does not help, then evaluate both error logs.
