Problems after activating a remote server

[Gotteshand]

Hello.

I have already opened a ticket, but maybe it will be faster here

I wanted to reactivate my old remote and now it won't allow me to connect.

I get the following message:  

I have already reinstalled TCAdmin and loaded a new config. Also deleting the remote and creating a new one does not solve my connection problem.

Do you have an idea what this can be?

Edit:

Done.

The security port must be set to 0.
