My.openhab on RPi3 not connecting - config issue?

I’ve searched the forum for this already and I’ve followed about every step I can find to troubleshoot but I still cannot get my.openhab to connect to my account from my Raspberry Pi.

This is what I’ve done so far:
-Installed OpenHAB 1.8.3 via apt-get
-Installed openhab-addon-io-myopenhab via apt-get
-set security to EXTERNAL in configuration file
-set network mask to in configuration file
-restarted, copied secret and UUID to my.openhab account
-removed openJDK and replaced with Oracle JDK version 1.8.0_101 and verified

I’ve restarted the Pi and still it only shows offline on my openhab account. I do get a DEBUG message shown in the list below:

Can someone point me in the right direction to debuging this?

Thanks for the help!


Configuration model ‘myopenhab.persist’ can not be found

Make sure you have a persist file for my.openhab.

I added the persistence file, added the rule to have it persist everything on any change but it still won’t connect. That message did go away though. I had a sample set up on my laptop and it would connect just fine but my RPi3 will not.

I do get a strange message about myopenhab not being authorized:
