nut-cgi Only shows Authorization Required message

Maintainer: @\neheb Environment: UBNT_E300 (CN7030p1.2-1000-AAP) / Ubiquiti EdgeRouter 4 / OpenWrt 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-23.093.57360-e98243e

Description:

After proper configuration of nut-monitor I installed nut-CGI, so I can now access my router /nut webpage, properly loading and showing stats and configuration links.

When accessing any of them, only a black page with "Authorization required" is shown.

I don't know what to do as the logs show that nut-monitor is properly connected to remote UPS (with authorization) and nut-cgi doesn't have any property for authorization.

What may be I missing?

Thanks!

Your device is perfectly supported by latest OpenWRT 23.05.5 , if you still encounter problems after upgrade feel free to adjust your post with supportable numbers.

After upgrading I'm getting this error when clicking on menu option:

  Near here ----------------------------------------^

I tried uninstalling and reinstalling luci-app-nut (forcing files) but no luck.

Maybe it's related to a leftover, but I'd need a little guidance to ensure everything is clean before retrying.

Not related to initial issue, approach forums.

Approached and fixed, thanks, now on OpenWrt 23.05.5 r24106-10cc5fcd00 / LuCI openwrt-23.05 branch git-24.313.38121-76e4eca

Error is still there, I just get an Authrization Error when browsing: http://myDevice/cgi-bin/nut/upsstats.cgi http://myDevice/cgi-bin/nut/upsset.cgi

The UPS client seems to be working properly and connect to the remote UPS network server

Web log would be nice to add..

[cconde]

Sorry mi ignorance, the logs from the web browser?

In the console I only see the following: http://*****/cgi-bin/nut/upsset.cgi

That's it, the only line there.

I've tried adding a basic authentication by prepending "user:pass@" but still having the same negative result.

I have to say I'm absolutley lost tryinig to understand which authorization is it referring to:

• My user is logged to openWrt device before I open the Nut CGI (indeed I use LUCI web page link).
• The client is logges to the UPS server.
• There's no authentication field I can populate on the Nut CGI tab at LUCI page

Thanks

I was also having trouble with this, and found this issue in my searches. I had been trying the username/password combination(s) which I had just configured in /etc/config/nut_server for the basic authentication when trying to access nut-cgi, which consistently failed.

I finally just tried my openwrt login for it and that's what actually worked.

So I think you just need to re-authenticate with openwrt to access nut-cgi (maybe it doesn't use the same cookies?)

Thank you! This worked for me and I never would have expected it would be the OpenWRT password it wanted. I don't much like the idea of needing to use the router's admin password for security/password saving reasons. I wonder if there is a way it can use the normal ups user login instead (since I have a view-only user from nut-server for that).

@nx6 There isn't from the GUI (that I recall), but if you edit /etc/httpd.conf you can use a user:password of your choosing (not sure what hashes are available for that file though, these days, as it's a uhttpd configuration that was used for legacy reasons when uhttpd was relatively new.
