Everything works perfectly until my IPv6 address changes

So, I had to restart the server and I just ran "sudo /sbin/sysctl -a | grep use_tempaddr" and this is the output:

Code:

net.ipv6.conf.all.use_tempaddr = 0
net.ipv6.conf.default.use_tempaddr = 0
net.ipv6.conf.enp1s0.use_tempaddr = 2
net.ipv6.conf.lo.use_tempaddr = -1
net.ipv6.conf.wlp2s0.use_tempaddr = 0

I double checked sysctl.conf and it definitely has "net.ipv6.conf.enp1s0.use_tempaddr = 0" in it, everything else in the file is commented out.
A new ip was assigned at reboot, so I guess I'll have to wait another 24hrs now to see what happens.
