Anywhere access issues

Im running a Orbi RBK 753 system with one router and 3 satellites so satisfy the needs of my old home. I work away for 6 month of the year and need to access my router to reboot and check on a regular basis to keep non tech family up and running with internet. 

for some reason when i go to anywhere access i get the message

"Some error occurred while enabling/disabling Anywhere access" 

Has anybody experienced this issue and do they have a fix? I've already been through to support with very little luck and understanding of my issue
