(Solved) My Servers - Showing Unavailable

[Lucky3058]

My router went through a reset last night and even after renewing the DNS and restarting the UNRAID api, I still cannot get it to show in My Servers.

What changed? Did the server's IP address or your WAN IP change? (honestly, it shouldn't cause a problem either way, just wondering what the significance is of the "reset")

Let's reboot Unraid, just to start fresh after the reset.

 

Can you show a screenshot of what you see when you click your username in the UPC (in the upper right corner of the webgui)

 

Also show a screenshot of this server in the My Servers Dashboard: https://forums.unraid.net/my-servers/

Rebooted the server just now. Screenshots attached. Still not showing available in My Servers.

Thanks, that was super helpful. Would you please check the My Servers Dashboard again, you should now have a Local Access url instead of "Access Unavailable"

Yeap just checked this morning and looks like this is fixed, what did you have to do?

We had bug affecting servers that did not have SSL enabled, your router change was just a coincidence  Thanks for reporting it.

ljm42 - So it shows correct under My Servers however when I click on local access to go to my custom URL it does not show the GUI page.

What url do you normally use to access the system, and what url is it offering you?  (replace abc123.unraid.net with the text "hash.unraid.net", we don't want to post your personal hash url publicly). 

 

Exactly what error message do you get when you click the url it offers you? A screenshot is fine too.

 

Also, please upload your diagnostics (from Tools -> Diagnostics)

Right now I am using the host IP of the server to get into the GUI. I used to use hash.unraid.net. And the error page states site cannot be reached (DNS_PROBE_FINISHED_NXDOMAIN).

I suspect that after the changes with your router, you might have issues with DNS Rebinding.

 

Please open a web terminal and type:

  host rebindtest.unraid.net

 

If the result looks like this, then all is good:

root@Tower:~# host rebindtest.unraid.net
rebindtest.unraid.net has address 192.168.42.42

If you get something else then you need to figure out how to disable DNS Rebinding on your new router.

oh sorry, I just remembered Unraid 6.9.2 doesn't have the "host" command. Let's use "ping" instead:

ping rebindtest.unraid.net

 

after a few seconds you can press "ctrl c". If DNS Rebinding is NOT a problem you will see it resolve to 192.168.42.42:

root@ODROID:~# ping rebindtest.unraid.net
PING rebindtest.unraid.net (192.168.42.42) 56(84) bytes of data.
^C
--- rebindtest.unraid.net ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1044m

 

If it does not resolve to 192.168.42.42 then you need to figure out how to disable DNS Rebinding on your new router.

Forgot about the DNS rebind protection. Verizon reset it back to on by default on the Router FW upgrade. Disabled it again, ran ping a second time and all good to go. Might want to let others know who have Verizon Fios with a G3100 router that also gets the upgrade to go back and re-disable that feature.
