No internet connection - Transferred hardware

[ibsailn]

Transferred my disks and usb drive to a new machine (significant upgrade in hardware).  Have had intermittent issues with network connectivity.  Can always connect to GUI, but ability of server to see the internet seems to be variable.  Plex docker was connecting 3 days ago, but I can't get it back now.  Not sure what changed.  I don't think I changed anything in any network settings or unraid settings.

 

I have tried static as well as dhcp.  I have tried defining DNS servers.  I tried to add a route per some prior post, but didn't seem to be able to get that to take.  I have downgraded to the prior release.  I am largely out of ideas now.  Diagnostic file attached.

 

Appreciate any help.

Oh, router is a Netgear Orbi.  Static address defined per the MAC address in the router software.  Fast fiber internet and unraid server is hardwired.  Never had any problems with network issues prior to changing to the new motherboard.

It appears to be working correctly, did you try accessing the server using the IP address?

[ibsailn]

Sorry if I wasn't clear.  I can access the server gui just fine.  The issue is the server can't access the internet, so no community app access, plex server can't connect to plex to login, can't download vertigo, etc.

Vert.io.....autocorrect.

Try setting the DNS servers manually, or reset lan config by deleting/renaming network.cfg and network-rules.cfg (if it exists) both on the config folder of your flash.

had tried setting dns previously with no luck.  Renamed network.cfg (no rules file) and no change.  can't ping google.com or 8.8.8.8.  Can connect to the GUI just fine, but unraid can't see the internet.  can ping local network machine no problem.  Might try a fresh unraid install on a new stick (trial version) and see if that works, but does anyone else have any ideas?

 

[ibsailn]

tried a fresh usb with brand new unraid install.  that one can't connect to the internet either (no pings and registration page shows it can't connect so server).  Now I really have no idea.  Might be a router issue, but I can't see any issues there nor can I think what could possibly be the problem.  Has anyone ever had a NIC that would connect locally, but not to the greater internet?  Doesn't make any sense to me.

delete the network.cfg file on USB in the config directory and restart and let UNRAID recreate, then configure your network settings again.  also delete any vfio-pci.cfg

this is what i had to do.

Might be a router issue,

I would say this is the most likely, if it does the same with a new flash.

Oddly when I put the original usb back in it connected to internet again......very odd as this last time I didn't change anything, but might be my router acting up as I am now having connection issues with other random devices.  Thanks for all the help.  Hopefully it keeps working.  Now I just have to fix my plex docker as I broke it trying to troubleshoot this issue.
