I have an odd problem. My IP settings are not carrying through a reboot. This happened on 5.3, so I upgraded to 5.3.1 thinking that it may fix the issue. It has not. When I reboot the server, I use the backup option. I also have a problem getting into the WEbUI, but I think that if the ip problem gets fixed, it may fix the other one as well.
The AIO IP settings is a known bug were network settings may randomly reset on reboot.
For the Web UI issue, it is possible that /var/log is full causing the Web UI to not load.
Run this command to check disk space.
df -TH | grep -v “loop”
In LiveNX 5.3.1 , admin username do not have permission to delete logs files in the AIO. Please open a support ticket using the link below.
