After the latest firmware V3.203 I can not log into Luci, I tried to install Luci again and I get an error, who knows the solution.

Maybe you can get a pc and ssh to the router to reinstall luci.

opkg update
opkg install --force-reinstall luci

Cannot really see the actual error in the video. But seems some packages failed to install.

Try going to Applications - Plugins and Update from there then try installing from Advanced Menu again.

This does not help, I understand that the necessary components are missing from the repository.

Seems E750 cannot connect to our server.

Does it has Internet? Or vpn or carrier limitations to access the Internet?

7

Yes, there is Internet, vpn is not used.

Can you try the following command and give me output?

ifconfig
ping 8.8.8.8
ping google.com

If necessary can I have a remote check using anydesk or teamviewer?

Yes, I can bring it home, let’s agree on a certain time and date.

At least https://fw.gl-inet.com/releases/v19.07.7/packages-3.0/ath79/glinet/Packages.gz is downloadable.

Is there anyway that you can think of it is blocked by your carrier?

I don’t know what the problem was, but today everything was established, did you have any maintenance work on the server?

I am not sure. But as you can do it now hope it is solved by now.
