@Niggich For my setup (raspberry pi 2) something changed after the update, but when I changed my IP addresses to the IPv4 notation (remove ::ffff:
from your addresses) it worked again. Which format do the blocked addresses have in your logs (see below)?
@FreddeHamm Are you sure those CIDR numbers are correct?
When in doubt, check the output or logs (pm2 logs MagicMirror
or pm2 logs mm
if you used the old auto starting guide), there should be a line telling you which IP address was received. Also there are a calculators which transform your IP range to the CIDR notation.
