localhost:433... failed connection refused.

[P6Mole]

Guys,

I am very new to this idea of port forwarding, in fact I have just watched a youtube video done by what sounded like an 8yr old lad making it sound simple, well I`m clueless and in need of help.

I am unsure if I have a router problem, a Domoticz problem or I`m just not doing it right.

When I run wget localhost:8080 all loks good however when I run the same for 433 I get what you can see below.

pi@raspberrypi:~ $ wget localhost:433
--2017-12-30 23:29:36-- http://localhost:433/
Resolving localhost (localhost)... ::1, 127.0.0.1
Connecting to localhost (localhost)|::1|:433... failed: Connection refused.
Connecting to localhost (localhost)|127.0.0.1|:433... failed: Connection refused.

Within my Plusnet router I have setup portforwarding from and to 433 for both UDP and TCP

My Domoticz.sh file looks like the below.

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
DESC="Domoticz Home Automation System"
NAME=domoticz
USERNAME=pi
PIDFILE=/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME

DAEMON=/home/$USERNAME/domoticz/$NAME
DAEMON_ARGS="-daemon"
#DAEMON_ARGS="$DAEMON_ARGS -daemonname $NAME -pidfile $PIDFILE"
DAEMON_ARGS="$DAEMON_ARGS -www 8080"
DAEMON_ARGS="$DAEMON_ARGS -sslwww 433"
#DAEMON_ARGS="$DAEMON_ARGS -log /tmp/domoticz.txt"
#DAEMON_ARGS="$DAEMON_ARGS -syslog"

In my explorer I type HTTP://192.***.***.***:8080 and I can access Domoticz
If I type HTTPS://192.***.***.***:8080 I get

This site can’t provide a secure connection
192.***.***.*** sent an invalid response.
Try running Windows Network Diagnostics.
ERR_SSL_PROTOCOL_ERROR

which I suspect is correct.
If I type HTTPS://192.***.***.***:433 I get

This site can’t be reached
192.***.***.*** refused to connect.
Try:

Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED

I`m hoping that this is enough for someone to point me in the right direction.

Ben

You could try using a different port number such as 9443 or any port above 1024, change this in 'Domoticz.sh'.

Extra permissions are required to use ports below 1024 on many Linux systems.

If you are set on using port 443 someone else should be able to point you in the right direction.

Hello P6Mole,

There is a typo in your domoticz.sh file, the correct port for SSL should be 443.

And you can then reach it by HTTPS://192.***.***.***

Succes

Gents,

Ive tried 8443 and 443 (with the corrections now made) and I get the below.

pi@raspberrypi:~ $ wget https://127.0.0.1:443
--2017-12-31 16:23:15-- https://127.0.0.1/
Connecting to 127.0.0.1:443... connected.
ERROR: The certificate of ‘127.0.0.1’ is not trusted.
ERROR: The certificate of ‘127.0.0.1’ hasn't got a known issuer.
The certificate's owner does not match hostname ‘127.0.0.1’

Its still the same when using my web browser (chrome) on my windows laptop and my android phone.

Any further help would be much appreciated.

You have a connection, only the SSL cert is invalid, you can add an exeption in your browser.

Have a look at the Domoticz wiki page:

Well gents,

thanks for your help, I have sorted the issue out.

By editing the Domoticz.sh file within my Domoticz folder I achieved nothing.
When I looked into my Domoticz log it was still looking for port 443 which was in use by something else.
When I changed the port within the Domoticz.sh file init.d folder the changes took effect and I can now log in vie HTTPS.

Cheers

Ben

Excellent thread! Kudos to Ben for his follow up. Helped me a lot.

I found out there is yet another location where the port numbers for Domoticz are stored. It is located at /etc/domoticz. The file is called setupVars.conf and only holds the port numbers for HTTP and HTTPS. I needed to change the port number for HTTP since that has to be used by my PiHole. So changed the port number for HTTP for Domoticz in all three files. Now my PiHole can use port 80 without Domoticz interfering

Greetz,
