Hello,

we have several RUT240 with legacy firmware so I started to upgrade them one by one. Mostly the upgrade is done correctly and everything works but in two cases I am unable to access WebUI with Connection Refused Error (Chrome: ERR_CONNECTION_REFUSED). On first fault device everything else works (two VPN tunnels, port forwarding etc.) and on the second fault device I am unable to check because I wanted to set this up after upgrade. However because I have working VPN on the first device I tried to SSH into it and check uhttpd configuration but everything seems ok. I unsuccesfully tried to re-save configuration file and stop/start uhttpd service.

Thanks!

Hello,

I was able to SSH into first fault device and login thanks to HTTP via SSH (technique described here). In Firewall section -> Traffic rules -> there was ENABLE_HTTP_WAN disabled and ENABLE_HTTPS_WAN disabled. So I suppose these two rules are applied even when connecting via VPN tunnel. On the second device I do not have VPN so I will try to enable SSH via SMS Command and then the same technique.

Hello,

I assume you are trying to access the device remotely?

As described in the thread you have mentioned, did you try to edit those traffic rules vis SSH and enable them?

If you can afford to lose your current configuration I suggest to access the device via SSH and reset it to factory defaults by entering command firstboot.

You can also use the following SMS command to restore the device to its factory settings: <login_password> restore or command <login_password> sshon to enable remote SSH access.

Best regards

Hello,
yes this method works, but... I have tried upgrading another device today a this is the result...

Before upgrade I turned on "Enable remote HTTP access", "Enable remote HTTPS access" and "Enable remote SSH". I am sure these settings were turned on because I started upgrade remotely via public IP HTTP WebUI. I was also able to connect via VPN.

After upgrade I am no longer able to acces HTTP/HTTPS/SSH nor VPN remotely and SIM card doesn't accept SMS (I think it's data SIM only). But the device is on - it response on ping! So now I have to go there localy and turn everything back on. I think there must be something wrong during the upgrade procedure.

EDIT:

After physical restart is remote HTTP access working! So after upgrade there must be something wrong on first boot.
