My server is located on client premise.
I'm facing an issue, in that my service(node js) is not able to connect with redis.
If I'm checking the status of redis it's running fine.
Loaded: loaded (/lib/systemd/system/redis-server.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2023-02-15 14:16:34 EAT; 18h ago
Docs: http://redis.io/documentation,
man:redis-server(1)
Main PID: 3085148 (redis-server)
Status: "Ready to accept connections"
Tasks: 5 (limit: 19104)
Memory: 8.2M
CGroup: /system.slice/redis-server.service
I'm able to connect with the service manually from one server providing host and port.
But the issue is when my service is trying to connect so it's failing.
So can anyone help me in suggesting what could be a possible reason for the same?

I have a nodejs app that I'm running on a ubuntu server on an ec2 instance. The code for the app is just this...
app.listen(port, () => {
HorseRacingAPI()
FootballAPI()
AmericanFootballAPI()
setInterval(() => {
HorseRacingAPI()
}, 1000 * 120)
setInterval(() => {
FootballAPI()
}, 1000 * 120)
setInterval(() => {
AmericanFootballAPI()
}, 1000 * 120)
})
Each of the 3 functions makes a request to an API, reorganises the returned data, and then sends the data to mongodb.
When I run this on my computer, it works great, sometimes a function may fail like 1% of the time, but it runs again 2 minutes later and works. However, when I run this on the ec2 instance, after a couple hours, the ec2 instance fails and won't run the nodejs app again until I reboot the instance and restart the pm2 server.
The pm2 logs look like this...

Is there anything I'm doing wrong? I need this code to run forever basically, so what do I need to do to make this happen with essentially 100% reliability?
I am trying to run my code using pm2 and I again and again get the below error. I have provided the complete credential details in mongouri which has the username password the cluster name and the table name, also I have whitelisted my ip and now I dont understand why is this error coming. Any help will be appreciated

Your connection URI is wrong. If you are using Mongo Atlas it cannot end with :27017.
Please log into your admin panel and click "connect" and "connect your application":
http://prntscr.com/ql150h
Copy a fresh string and paste it instead of what you have now inside your app:
http://prntscr.com/ql15cp
If this does not handle contact their assistance, they will help you sort this out.
I am facing weird issue while connecting MongoDB running in a separate container from my nodejs server container, it displays
the following error while trying to connect to MongoDB

which clearly states that connection refused. The code works absolutely fine when I run all services locally.
connection to MongoDB through mongoose in following manner
const options = {
autoIndex: true, // Don't build indexes
reconnectTries: Number.MAX_VALUE, // Never stop trying to reconnect
reconnectInterval: 500, // Reconnect every 500ms
poolSize: 10, // Maintain up to 10 socket connections
// If not connected, return errors immediately rather than waiting for reconnect
bufferMaxEntries: 0
};
console.log(options);
mongoose.connect('mongodb://localhost:27017/tododb',options).then(
() => { console.log("connected !!!"); },
err => { console.log(err); }
);

Please guide where exactly I am missing. Thanks in advance.
Change the connection string "localhost" to "mongo-database"
mongoose.connect('mongodb://mongo-database:27017/tododb',options)
when you use docker-compose it creates two containers so localhost for node is different from localhost to mongo.
run "docker container ls" this will give you the mongo container name use that in the connection string.
I use docker to run redis on AWS EC2 and I use kue to connect to it at my node server.
But it shows error like below.
How could I fix this? I use redis-cli to ping to IP and GUI tool to connect redis are woring fine.
