Hello all-

I'm currently running 7.0.1, and I have had a flawless experience with Unraid for over a year and a half. I have been dealing with a drive error issue(https://forums.unraid.net/topic/191160-ata-errors-701/) , and I tried first to stop the array and then shut the system down to replace the SATA and power cables as recommended in another support thread, but the system locked up when I tried to stop the array. I was able to get it to gracefully shut down by tapping the power button, turned it back on, and then tried to shut it down, but it wouldn't. It hung on the web GUI for over an hour, and the server never powered down. I had to do a hard reboot, and once the system came back up, I did some googling and found that some culprits for now allowing a shutdown could be an open SSH session (not me), open terminal (possible, but after subsequent testing unlikely), or a docker container or VM preventing it from shutting down. I had been able to stop all my Docker containers, but when I tried to stop my single VM, a Home Assistant instance, the system completely locked up again. I've also tried stopping the VM service from the settings page, and selecting "safe mode" when rebooting, all with the same lockup. When the system locks up, I can't ping the server anymore.  

Now, I cannot log into the server web interface anymore; the browser just times out. My router sees the system with an active network connection. I cannot ping the server, it times out. I plugged in a monitor, keyboard, and mouse, and the system booted, on the display, and I can log in, but I don't know enough to know where to start troubleshooting from the command line. I did download diagnostics and will attach them. I've tried to get it to boot into safe mode via the display, and it does boot, but I still cannot access it via IP or ping the IP. I also tried to boot it into the GUI and GUI safe mode, but all I get is a blinking cursor on the display. I've also plugged in my laptop to the Ethernet cable, and all seemed to work fine network-wise on my laptop.

As my last-ditch attempt before submitting this, I've pulled all my USB "extras" (Coral, Z-Wave and Zigbee controllers, Bluetooth dongle), and my Nvidia RTX video card. I was able to boot into the GUI under safe mode (huzzah!). However, I'm still unable to access the server remotely via IP, nor am I able to pull up (any) website via my browser on the server display. I also happened to notice a message during bootup along the lines of "Eth0 - Device not found".

I'm at the end of my initial diagnostic efforts and not sure where to go next. Has the onboard NIC on the motherboard (ASRock - Z790 Pro RS/D4) failed...how would I test that? What should I look into next? Thanks for the assistance.

Try uninstalling the Realtek driver plugin

Try uninstalling the Realtek driver plugin

With my server shut off, I removed the USB, found the realtek8125 under config/plugins, and changed "r8125-driver.png" to "r8125-driver.png.bak".

No change, still can't access the server other than via display. Also, I still spotted the eth0 not found error mentioned earlier during the bootup scroll, however when I boot into GUI safe mode, under System Devices (via Tools) I see "Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5 GbE Controller (rev 05)" under IOMMU group 12.

That won't work, since it will leave the stock driver blacklisted, you should uninstall the plugin using the GUI mode, if you can't, also delete /config/modpobe.d/r8169.conf from the flash drive.

Ok, that seemed to have worked...sort of. From the display, I can now get to the internet, but I can't log in to the server from my laptop via the IP directly. Nothing has changed on my firewall rules. I can, however, log in to the server via my tailscale IP.

Try booting in safe mode, to rule out a plugin issue, mostly Tailscale in this case.

Thanks for your help so far. Booting up in safe mode GUI has the same result. Locally on the server I can access the internet, but I can't access the server via the assigned IP. The IP is assigned by my opnsense router, and the network config (ipv4 address and DNS assignments) on unraid is automatic.

To confirm if it's a config issue or an external problem, you can try redoing the flash drive, backup the current one first and then recreate it using the USB tool and just restore the bare minimum, like the key, super.dat and the pools folder for the assignments, also copy the docker user templates folder (\config\plugins\dockerMan\templates-user), if all works you can then reconfigure the server or try restoring a few config files at a time from the backup to see if you can find the culprit.

Okay, I've done a fresh install on a vanilla USB drive, and that seems to have worked. I'll start the process of sliding things over a couple items at a time to see what the culprit was. Thanks so much!
