Sheep

So as the title goes over the past 6 months or so my server has been randomly crashing the server still maintains power but I cannot access the WebGUI or ping the machine. A reboot tends to fix the problem for a little while but it has now got to the point that it has been nearly weekly. There seems to be no pattern to the crashes on random days and times sometimes my boot device doesn't get picked up and I have to change it to a different slot on the motherboard for it to work again. I have even tried one of these USB internal dual port USB plugs to see if it had something to do with it. It seemed to fix the problem for about a month but then the crashes started again. When the server is up it all runs perfect. I have turned on the abaility for the logs to be saved to the USB and have had a recent crash. But I am not that good at reading logs to try and determine the issue but nothing seems to be on there that would casue this issue any help would be much appreciated. I have uploaded my syslogs if that helps. syslog syslog-previous

So my Nginxy Proxy Manager has been working fine for months now, but for the past couple of days I have been getting this error. Any help would be much appreciated. I haven't touched it in ages, and I'm also now getting an "internal error" in Nginxy Proxy Manager if I try to get an SSL for my subdomains.
