Question

Hi All:

We have a RUT950:

root@CORS285:~# cat /etc/version

RUT9XX_R_00.06.08.6

The dropbear port was changed to 22222 and it works fine, we have ssh access.

When we try and connect to the WebUI we get this:

Bad Gateway

The process did not produce any response

I have checked and double checked the /etc/config/network and /etc/config/firewall files and they are correct.

We have 400 units deployed and this is the only unit doing this.

root@CORS285:~# netstat -a -t -n -p

The webservice is running on port 80 with PID 2108.

root@CORS285:~# ps -w | grep 2108

Its running.

We've rebooted a few times and it comes up the same.

Any idea on how to fix this?

Other than this, the router is working fine.

Cheers,

john

Hello,

You could try to create a backup of your current configuration with the command below:

• sysupgrade -b /tmp/backup.tar.gz

And restart your device to factory defaults using one of the options listed in this page to see if the issue persists, then reupload backup following instructions here using scp/WinSCP.

To restore backup, use WebUI or execute reupload it to the device and execute command below:

• sysupgrade -r /tmp/backup.tar.gz

You can try and update your device's firmware to 6.9.2 or later, if your device supports it, via SSH following these instructions.

Otherwise, I would like you to get a troubleshoot file from the device. Login to the device via SSH, execute the command below:

• troubleshoot.sh

Download the file using scp/WinSCP from /tmp directory and attach it by editing your question. The logs in the file might provide more details into the issue.

Best regards,
