HI,

Looking at the account there is only one device that has communicated today 4/9 - AP-PC The other’s have been 2-3 days ago since last seen.
Communication is done over ports 80/443. If the devices have been on in the last day try removing Avast and run this cleaner utility
https://www.avast.com/en-us/uninstall-utility
then reinstall and see if it helps. If not, post back and we will take a closer look to see what is happening.

Thanks!

Jeff
