Since 2 days is the following problem:

When I enter in a, it does so only after about 12 seconds.
Normally I would have to be in the channel immediately, which is unfortunately not the case.

Even if someone forgives talk power to me, I see that after a few seconds, just as in the chat messages.

The problem is not on the Internet, I've checked.

The problem also exists on only one server. For the other servers, these problems do not emerge.

The owner of the server told me it's up to me. But that can not be. I have the version: Client 64-bit!

In other versions, it has not worked. Can someone help me there?
I am despairing.
