The actual "issue" is way simpler, in my infinite wisdom I made the ARP static when I set up the router back when I first created the unraid server and 100% forgot I did that or even remember that it exists.

Okay, it seems like it was a router issue, because I disabled static IP for unraid server in WinBox and let it get a random IP and now it works WHICH I'M 100% SURE I DID YESTERDAY, but whatever. Now it works, thanks for the helps! The previously mentioned indeed fixed the issue, but it was a surface fix. The problem is that my MikroTik router did not update the ARP table (whatever that means) to the new mac. Executing /ip arp print revealed that 192.168.1.194 had the wrong MAC. Running /ip arp remove [find address=192.168.1.194] fixed the issue immediately.

But then SystemRescue wouldn't work either, it has the same mac (as I used it in the same hardware as unraid). Also I checked the router settings and I couldn't find any mac filter. I just tried SystemRescue again, and it stopped working (it did work yesterday), what

I already created multiple bare new installs, even with different unraid versions, none of it worked, but booting SystemRescue instead (same hardware) everything worked fine. What I did not try yet is a different pendrive, I'll try it now. Did not help, new pendrive without doing anything to it (other than installing unraid 7.2.2) does not work either.

I don't think it is a DNS issue, because I cannot ping IPs either (not even my router, but arping works on it), I also tried to change DNS from my router to 1.1.1.1 and did not help at all (my router can act as a DNS server). Result of cat /etc/resolv.conf: # Generated by dhcpcd from br0.dhcp nameserver 192.168.1.1 # Generated by rc.inet1 I found something interesting: Time sync seems to be sometimes working sometimes not, right now it says it could sync (i have time.google.com and pool.ntp.org set). Clock is synchronized using 1 NTP servers, time offset is < 1 μs But for example if I try to download a plugin it says network failure plugin: installing: community.applications.plg Executing hook script: pre_plugin_checks plugin: downloading: community.applications.plg ... plugin: community.applications.plg download failure: Network failure Executing hook script: post_plugin_checks After I changed settings in Date and Time it started showing Clock is unsynchronized with no NTP servers again

I think that diagnostic was with USB ethernet (so eth1 had the connection), attached a diag where the USB is not connected and the cable is in eth0 blackserver-diagnostics-20251203-1034.zip

I recently bought an ASRock Pro B550 PRO4 motherboard to use with my old Ryzen 9 3950X CPU for the unraid server I have. The old system worked flawlessly, but with the new motherboard I cannot access internet or even ping my router from the unraid server. The weird thing is that I can ping the server (and even connect to it) from my PC. I have a random SystemRescue laying around, when I plugged it in and booted to it everything worked fine: I could ping the router and also could reach the internet, so it is not a router/hardware issue. I tried the following already, but none of it fixed/worked: Enable/Disable bonding/bridging. Change to/from static IP (so tried both DHCP and static) Connect a random ethernet USB dongle, same thing, could reach the server, but the server could not reach outside Load r8168 driver from https://github.com/jinlife/unraid-r8125-r8152-driver, and disable r8169 driver Update unraid to latest version 7.2.2 Downgrading to unraid 6.12.15 Safe mode Different network cable Delete /config from pendrive (factory reset?) Various random thing copilot told me to do: Routing table is correct, shows my router IP arping works, ping doesn't ethtool shows 1000Mb/s full duplex, link detected Updating kernel to 6.17.0 from https://github.com/thor2002ro/unraid_kernel, unraid works, and I can see the new kernel, but the network is still not good Please, someone help me out, I'm out of ideas.
