August 2, 20232 yr Hello, my problem with the unexpected power off has been solved by a motherboard replacement. Now I unfortunately have the problem that my Unraid web ui is sometimes not accessible, this usually occurs 1 hour after the start. When I ping my server it is not reachable, but the VM are still running. After a power reset of the server it runs normal again, until it occurs again. Do you have any idea where the problem could be? I have attached the diagnostic file and the syslog. syslog tower-diagnostics-20230802-1245.zip

August 2, 20232 yr Community Expert See the linked thread, mostly depends on how many ports you need.
August 4, 20232 yr Author Hi, I have now replaced the Sata controller with a controller with asm1166 chip, now I have already faster speeds. Unfortunately my server has restarted again tonight, I have attached the syslog. Do you have any idea where the problem could be? syslog
August 4, 20232 yr Author Hi, okay, at the hardware, however, I can not think of anything I can still exchange, motherboard has been replaced with a new one, power supply has already been tried two new ones, memory has been checked with memtest, CPU is also good, what I noticed yesterday that hard drive "sdh" has a Smart Error, could that also indicate?
