Hi everyone,

I’m experiencing a strange issue with my Unraid server. A few weeks ago it was running flawlessly, but after a recent reboot I ran into the following problem:

• Immediately after reboot, I can access the Web UI (via browser) and my network shares from my MacBook without any issues.

• About 15 minutes or somthing later, nothing changes on the server, yet I can no longer access the Web UI or network shares.

• When I enter the server’s static IP in my browser, I only get a plain “200 OK” response, no UI (picture below) and unable to access network shares.

• I can still ping the server IP successfully, and all services appear to be running normally on the server itself.

Has anyone seen a behavior like this or can suggest what might be causing my Unraid server to become inaccessible on the LAN after it has been idle for a short time? Any pointers on logs to check or settings to adjust would be greatly appreciated!

Diags ap+pear to be after a reboot, were you having the issue at that time?

Right after a reboot, I can access the Unraid server without any issues, then wait about 15 minutes later it becomes inaccessible again.

I tried several reboot and it's all the same. Right now i can not access my Unraid.

Enable the syslog server and post that after it happens again.

I already enable it, and the problem is happening right now.

I'm sorry if I'm wrong but there is no new log generated when I could not access to Unraid via web browser

My Unraid has 2 NICs

• One is 10.10.66.88 which i dont use very often, it just a NIC to connect Unraid directly to my Mac when i need to do 10Gbps highspeed task

• Another is 192.168.10.103, which is connected to my router, and this is where the problem is. I could not access to my server by this IP, either web browser or SMB

You need to input the local server IP on the Remote syslog server field, see the linked instructions.

Oh i got it. Thanks. I'll be back after the problem happen again

Hey i got the error. It said that there is no mode-log.js file. Do i need to re-install something?

Ignore that, if the config is correct, it should still work, you can also check if it's saving a syslog to the system share.

Yes, syslog is being saved to my system share.

I dont know why but now I can access to Unraid properly. I did not change anything in config

I got the log when I could not access Web UI/SMB. It said "ACPI action up is not defined"

I have just updated the OS the see if its fixed, after rebooted I could access my server, and after a while I could not access it, and then wait for a few minutes I could access it again.

I dont know what's wrong with my server, maybe my network problem?

Ignore this. It’s harmless. You pressed the ⬆️ arrow key and the keystroke is not recognized. Happens with some keyboards

Oh thanks. I have been trying so many tweaks like reloading nginx or disable plugin, nothing changed

I found the solution, just change the IP of Unraid server and tthe problem is gone
