Luci ( uhttpd ) - channel 3: open failed: connect failed:

[h0ppus]

Hi everyone,

I would appreciate some help with some errors after upgrading my openWRT box.

I have upgraded from 19.7.2 to 19.7.7 and Luci is not working on HTTPS.

After the upgrade, it worked on the default 192.168.1.1:80 however when I restored my previous config from 19.7.2 Luci stopped responding as before and the logs were showing :

daemon.err uhttpd[6325]: Error: No sockets bound, unable to continue

I did some research on the internet and noticed that the default /rom/etc/uhttpd had some different lines and I have copied the default to my current config /etc/config/uhttpd and Luci started to fail with the below :

daemon.err uhttpd[6382]: /usr/bin/lua: /usr/lib/lua/luci/ccache.lua:6: module 'nixio.fs' not found:

I have again after some research on the archives found a solution :

root@R1 /root > opkg install luci-lib-nixio
Installing luci-lib-nixio (git-21.072.27936-731d2e3-1) to root...
Downloading http://downloads.openwrt.org/releases/19.07.7/packages/arm_cortex-a9_vfpv3-d16/luci/luci-lib-nixio_git-21.072.27936-731d2e3-1_arm_cortex-a9_vfpv3-d16.ipk
Configuring luci-lib-nixio.
root@R1 /root > /etc/init.d/uhttpd restart

Luci then started to work and become accessible on port 80 however no luck on port 443 and started to fail with the below on the shell every time a connection is attempted:

root@R1 /etc/ssl > channel 4: open failed: connect failed:

I have followed the wiki and reissued Luci's certificates but the above error still happens.

The uhttpd config is as below :

root@R1 /etc/ssl > uci show uhttpd
uhttpd.main=uhttpd
uhttpd.main.listen_http='0.0.0.0:80' '[::]:80'
uhttpd.main.redirect_https='1'

uhttpd.defaults.ec_curve='P-256'
uhttpd.defaults.country='ZZ'
uhttpd.defaults.state='Somewhere'
uhttpd.defaults.location='Unknown'
uhttpd.defaults.commonname='OpenWrt'

I am not sure how to fix the error above and any help would be appreciated.

Luci is not working on HTTPS.

Have you installed luci-ssl package?

(Default in 19.07 is without SSL capability...)

[h0ppus]

The package luci-ssl was not installed, after installing it and changing the Luci's config it is now serving HTTPS as expected

root@R1 /etc/config > uci show uhttpd
uhttpd.main=uhttpd
uhttpd.main.listen_https='127.0.0.1:443'
uhttpd.main.redirect_https='1'
uhttpd.main.home='/www'
uhttpd.main.rfc1918_filter='1'
uhttpd.main.max_requests='3'
uhttpd.main.max_connections='100'
uhttpd.main.cert='/etc/ssl/r1.crt'
uhttpd.main.key='/etc/ssl/r1.key'
uhttpd.main.cgi_prefix='/cgi-bin'
uhttpd.main.lua_prefix='/cgi-bin/luci=/usr/lib/lua/luci/sgi/uhttpd.lua'
uhttpd.main.script_timeout='60'
uhttpd.main.network_timeout='30'
uhttpd.main.http_keepalive='20'
uhttpd.main.tcp_keepalive='1'
uhttpd.defaults=cert
uhttpd.defaults.days='730'
uhttpd.defaults.key_type='rsa'
uhttpd.defaults.bits='2048'
uhttpd.defaults.ec_curve='P-256'
uhttpd.defaults.country='ZZ'
uhttpd.defaults.state='Somewhere'
uhttpd.defaults.location='Unknown'
uhttpd.defaults.commonname='OpenWrt'

I did not backup the packages installed prior the upgrade which proved being a big mistake. I am going to check it before upgrading my other two openWRT boxes.

Thanks for your help.
