Error when installing voicerss and marytts

Hello All
openHAB 2.5.9 Release Build
Raspberry PI 3B+

I tried installing these two and now keep getting this in the log:

2020-10-07 18:27:03.109 [ERROR] [core.karaf.internal.FeatureInstaller] - Failed installing 'openhab-voice-voicerss, openhab-voice-marytts': Error:

	Error downloading mvn:org.openhab.addons.bundles/org.openhab.voice.voicerss/[2.5.0,2.6)

Any assistance will be highly appreciated.

Hah - DNS error on router - Fixed now.
