I have installed Red5 server (0.9.1) on the Linux server, but I am having some problems to install any app on my Red5 server using the installer.
The front page (http://my.ip:5080) works great, but when I try to go to the installer (http://my.ip:5080/installer), I get an error message like this:
Trying to connect
Net status: NetConnection.Connect.InvalidApp
Net status:NetConnection.Connect.Closed

I have deployed my website to a Digital Ocean droplet (Ubuntu 20.04 server).
Everything was working fine. Today, I did some changes to the website in my local machine. So I pushed the changes to GitHub and then cloned the GitHub repo again to the server. Then, I installed the dependencies and restarted PM2.
Now, when I visit my site https://sundaray.io, I get the following error.
The following is the error log.
How can I fix the error?
Simple meaning is
No HTTP server response, your Node Http server is not answering requests.
502 gateway mean server and Nginx is getting your request but there is issue with upstream.
you can use the command to show the logs of pm2
pm2 show
the application might be crashing or internal server 500 error.
I'm trying to run for the first time my React/Ionic app on an Android Emulator using Capacitor. The app should connect to my local Node server using Axios.
While my app started successfully on the emulator, all server requests failed with Msg: Error: Network Error
Here's the steps that I did:
I configured Axios to connect to http://10.0.2.2:3001 instead of localhost, but the requests still fail
I opened the url http://10.0.2.2:3001/api in the Android Emulator Chrome browser, and it succeeded in connecting to my server and returning a response
I tried adding to my capacitor.config.json file the following conf, but my app still fails
"server": {
"allowNavigation": ["10.0.2.2"]
}
Would you have other advices I should try to make my app connect to my local server? Thank you
After searching, I found the solution in another SO question :
The problem comes from the fact the my app uses http instead of https requests which Android forbids by default, starting with API level 28.
To allow http requests, I added android:usesCleartextTraffic="true" to my app's AndroidManifest.xml
Reference: https://developer.android.com/guide/topics/manifest/application-element#usesCleartextTraffic
if you use instances on cloud, modify host file, on linux the rute is : /etc/hosts
add this line:
localhost < ip-public-your-instance >
Description
I have a Node server and React App running on my notebook Ubuntu 18.04.
Notebook ip is 10.0.0.101
I tried to connect my desktop to this server on the same network
Desktop ip is 10.0.0.100
Node is running on PORT=3333
React is running on PORT=3000
I can ping my notebook from my desktop but when I try to connect to node using Insomnia or to http://10.0.0.101:3000 from my desktop I cannot reach.
Errors
When try to connect to backend with Insomnia
Error: Couldn't connect to server
When try to connect to app on 10.0.0.101:3000
ERR_CONNECTION_TIMED_OUT
What I've done
I already changed the node listen and specified the port and the ip but it didn't work.
I tried to use my phone as router and connect from my phone to react on my notebook and also didn't work.
I've tried so many things since I can't remember them all.
I'm also creating a react-native app and when I try to connect to my mobile using Expo, it just works using tunnel, but cannot get data from the backend.
Please save me.
Thanks
After making many failed attempts, I realized that the problem was in my notebook.
I checked my firewall and it was disabled and still cannot get acess to my notebook on LAN. But finally I discovered what have to be done
Solution
You have to open the specific port for TCP traffic
Ubuntu:
sudo ufw allow <PORT-NUMBER>/tcp
or for Red Hat Enterprise
firewall-cmd --add-port <PORT-NUMER>/tcp

I write my server file with node.js and has successfully test in my local , i install node.js and mongoDB plugin on my server , that is windows, but when i type server url instead of my ip in my android app I can't find server and get error server not found
Please help me
An overview of my setup:
A socket.io/node server is being hosted/ran on a computer in my local network.
An Ionic app is attempting to connect to the socket.io/node server to send/receive messages.
If I run the app in the browser with 'ionic serve', I am able to connect to the socket.io/node server successfully.
If I run the app in the emulator or on my device, I am only able to connect to the socket.io/node server if I add the -l (livereload) flag (ionic run android -l).
Originally, I hosted the node server on a heroku instance. I had no troubles connecting with this setup from browser, phone, or emulator. I had to switch to running the node server on a local computer so I have access to a local database.
Any ideas what is going on?
I fixed it by adding 'http://' to the beginning of the connection string.
Not sure why Ionic's livereload enabled me to connect without the 'http'
