Looks like caused by your Java version

This java version will be SLOW as hell! You should use a JVM with hotspot, eg from here
adoptium.net
Also your encoding is not correct and you will have issues with special chars in filenames

Any VPN/Proxy on your NAS?
You can also try BouncyCastle, enable Settings->Advanced Settings->GeneralSettings.preferbouncycastlefortls
but you should switch JVM definitely else you won't be happy with it
