Issue SSH Tunnel for MySQL

[Astreon]

Hi Community,

i have an internal Server thats providing MySQL for me. This can be accessed over the internal network on 10.10.10.201. On my Pleskserver, if i will connect to it with mysql -u root -p -h 10.10.10.201 it will work beautiful. But if i try to connect with Software like Navicat or MySQL Workbench over an SSH-Tunnel this will be denyied of some reasons.

On the Server there is a standard SSH-Config, in Plesk i have temporary turned of the Firewall, but it didn't work like on other Servers. In the syslog or authlog there are also no entries for this problem.

Using: Debian 9.3.x
Plesk: 17.8.11

This is the Navicat:Errormessage

Navicat on an outside machine correct?

Do you have the port for the external IP mapped to the internal IP?

Yes using Navigate on my PC, to connect to a Server B (only accessible over internal Network) trough the Pleskserver which has a second Networkinterface that connect to the Internal Network. (On other Servers this did work, but on Plesk not). Firewall is turned off.

Where do i must set this IP-Mapping ?
