If I kill the odhcp6c process it will spawn a new process and IPv6 connectivity is restored for a while but in like 1-3 days It's diving again.
I have logged a task at Teltonika but they haven't been able to pinpoint where the issue is. I have tried starting the process with -v but it seems to not be able to give any more details in the logs.
The process is started with these arguments: odhcp6c -v -s /lib/netifd/dhcpv6.script -P0 -t120 qmimux0
Is there anything I can do to enable more logging to pinpoint the issue?
The /lib/netifd/dhcpv6.script file is quite massive:
