DDNS | Implement a modern Dynamic DNS server from scratch | DNS library

I am trying to send data from Flutter to Node-RED (to Raspberry Pi) over HTTP (not HTTPS). The URL http://bierbrauserver.ddns.net is from NO-IP (DDNS). The transfer to a test server from a Youtube Tutorial works fine. But when I change the URL from "https://reqres.in/api/users" to "http://bierbrauserver.ddns.net:1880" I get no input in the debug window of Node-RED. I tried in the AndroidManifest.xml to add the entry so that http is allowed, but that didn't solve the problem either. Furthermore I checked the port forwarding in the WLAN router configuration of the network where the Raspberry Pi is located. Here a port forwarding of HTTP and 1880 (Node-RED) was configured. The connection of the IP addresses should be ok, because I can access a database from an external port, which is also located on the Raspberry Pi. Can it be that only httpS post requests are possible ?

I am working on implementing a smart home Alexa skill using Node red. I followed a set of tutorials to the t (tutorial). However, when I go to link the account, I am getting back the dreaded "We were unable to link at this time"

I have been going back and forth on so many parts to track down the issue. Here is what I have confirmed so far:

1. Alexa app is able to open my authentication URL.
2. I am able authorize and provide authorization code with redirect URL.
3. Alexa is requesting for access token using authorization code previously provided.
4. I am able validate authorization code and response back with access token and refresh token.

Here is what I am using for the redirect URL:

my registrar is changing API and I am trying to automate my DDNS file.

Via the API I can authorize and get all my domain data:

I am configuring my first AzerothCore server. I got to the part where I configure the acore_with database's realm list table's address field. Can I use my ddns hostname here or do I need to use the dynamic public IP and change it every time my IP resets?

I've been looking for a while, unfortunately without resolution: how to switch to HTTPS a lighttpd server functional in HTTP on a Raspberry Pi?

Important to know: this website being connected to my router, it is accessible thanks to a dynamic DNS under a domain: name.ddns.net (also ports 80 and 443 are open on this router).

Here is my process:

• generate the keys:

For faster prototyping of my code, I would like to provide my laptop address as an endpoint to the http webhook API (Base URL) of the website cloud.thethings.network.

For this, I setup a ddns on noip.com and connected my tp-link router with my noip-account. So right now, I have sth. like myneedddns.ddns.com that forwards to my router.

I’ve also set port forwarding in my router to access my laptop and reserved a static IP for the laptop:

However, I can not provide a format like xxx.ddns.com:801 on thethingsstack. From there I can probably handle how to receive the request with flask or django.

How would you approach my goal?

I want a friend to access to my oracle DB through DBlink. Im new to Databases, so i could not make this work.

I suppose i have to create a listener with my public IP or so. So i used the NET configuration wizard to create a service name. I used the public IP but the wizard throws a timeout when trying to connect. I tried to create a Listener with my public IP in the listener.ora in por 1522 but it did not work eaither

What i have done:

1. I checked the listener.ora, it has a LISTENER with my local ip (192.168.1.134) and the port is 1521
2. I checked the tnsnames.ora, it has the same IP and port of the listener.
3. I made the port forwarding in my router.
4. I used the wizard to create a Listener with public IP.
5. I used the wizard to create a service name with public IP address but it cannot connect

TNSNAMES.ORA:

I started using K3S, so I'm an absolute noob. Now I'm wondering how I can create the .yaml Files for pods by my own or use a docker image. (Couldn't find detailed infos about that)

I want a OpenVPN or any other suggested VPN Server running, so I can access my home devices from anywhere. It would safe a lot of headache and time, if someone could be so nice and help me a little.

Before, I've had a OpenVPN Server running, when I only had 1 Raspi. But it looks like everything from the install to the config changed with my k3s Kubernetes Cluster.

How I Made my k3s Cluster with Rancher: https://youtu.be/X9fSMGkjtug

Tried for 3hrs to figure it out, found no real step by step guide for beginners...

I already have a Cloudflare ddns script running to update my Domain with correct IP.

Thank you very much!

A little background: I have a Tesla Powerwall which has it's own built in web server that can be accessed on the local network. It only allows SSL connections and uses a self signed certificate. I have setup port forwarding that allows me to connect to the web server remotely. For a while, i've had working node.js apps both on a local Pi and also a remote AWS instance that made requests to the Powerwall web server to retrieve bits of information.

Since yesterday, Tesla updated my Powerwall and now everything has stopped working. I can only assume they have changed something regarding how the web server handles it's self signed SSL certificate.

Firstly, my Pi running on the local network would not make successful node.js requests to the local server. I managed to get this working by adding an entry to my /etc/hosts file like this:

192.168.1.42 powerwall

and now my node.js app can successfully connect again using https://powerwall

When using Safari or Chrome to connect remotely, I can connect if I use my IP address (After trusting the self signed cert) but cannot connect when using my DDNS address that points to home. (I have confirmed the DDNS is working). It gives me the error:

Safari can’t open the page “https://home.xxxxxx.com:4444” because Safari can’t establish a secure connection to the server “ home.xxxxxx.com”.

My AWS node.js app will not connect regardless of me using the IP address or DDNS address giving me the error:

Client network socket disconnected before secure TLS connection was established

This is how I am trying to connect:
