Error setting up client lease upon performing connect - Ubuntu

Trying to host localhost server:

OS: Ubuntu 20.04

Main Java Version is Java 11

For starting Server and Client i use a secondary Java 8 Version, for that i changed startClient and startServer .sh scripts:

```
#!/bin/sh

PATH=/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/:$PATH java -Xms256m -Xmx512m -Dfile.encoding=UTF-8 -jar ./lib/mage-client-1.4.50.jar &
```

```
#!/bin/sh

PATH=/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/:$PATH java -Xms256M -Xmx512M -Dfile.encoding=UTF-8 -Djava.security.policy=./config/security.policy -Dlog4j.configuration=file:./config/log4j.properties -jar ./lib/mage-server-1.4.50.jar

```

Error:
