Added.

Thanks you so much. It worked for me.

That IP and port are still whitelisted in Tommy's firewall, and your site seems to be working fine for me.

Currently, my nodejs application access is still corrupted as above (There are times when the access does not appear error).

I am trying to find the cause. Can you give me a log of my nodejs application.

I tried blocking all outbound connections on my local environment and I got the following error

My MongoDB is stored as "Replica Set - 3 nodes" so when the primary node (104.40.21.132:27017) fails to connect, it will redirect to the other two nodes but the firewall will block it. 

So can you please add secondary node ip 104.40.21.243 and 138.91.174.29 to the whitelist in Tommy's firewall.

Thanks very much

TCP port 27017 has been opened to 104.40.21.132 on Tommy's firewall.

 

It looks like your site is working now. https://vnu.hdhquangnam.tk/

The "Incomplete response received from application" error reappeared while accessing my NodeJS application. Please let me know if the firewall allows access to "104.40.21.132" with port 27017.

If you allow access via ip as above, please add access by allowing access via domain name (cluster0-shard-00-00-6habu.azure.mongodb.net).

TCP port 27017 has been opened to 104.40.21.132 on Tommy's firewall.

Thank you so much.

The ip is the ip that your script tries to connect to. For instance if the database was hosted on Tommy the ip would be 65.19.143.6.

 

The port is the port that your script tries to connect to. For instance if you were using mysql on the default port it would be 3306.

IP: 104.40.21.132

Domain Name: cluster0-shard-00-00-6habu.azure.mongodb.net

Port: 27017

Thanks you!

What IP and what port?

I really don't understand what you mean.

Mentioning that you're connecting to a remote mongodb database would have saved me like 45 mins. All outbound ports are closed unless you request access. The reason any pages with database connections are timing out is because you never requested permission to access a remote database so the firewall is blocking you. I'm honestly a little annoyed with you right now for wasting my time.

I tried uploading the page to heroku. Everything on it works as I expected.

I think I have granted remote database access to my mongodb database.

Please help me . Thank you

I apologize for not stating the problem. Can you help me open the firewall in this case?

Thank you very much

What is the url of your nodejs page?

I visit the page https://vnu.hdhquangnam.tk/ also has the same results as the page https://vnu.hdhquangnam.tk/test.

But when I accessed https://vnu.hdhquangnam.tk/about, the result was running as I expected

Great! Let us know if you still need any help.

Sorry but I want help in the case of status code 502 (2nd image).

The page that returns status_code 502 is the incorrect page for me

The first time your node application is accessed it will take a little longer to load, but it will cache the website and subsequent visits will load much faster. After some time has passed without any page views your node application will automatically uncache itself to reduce load and memory usage on the server. If you make changes to your application, and find that the changes aren't appearing when you view the page in your browser it is because an older version of your site is cached. You can force your node application to restart and load any changes by doing the following:

 

Create a /tmp directory inside your node application directory.

 

/home/username/node/tmp

 

Inside that /tmp directory create a file named restart.txt.

Now refresh your browser and the changes should show up.

 

Here’s another note from this site that I just found earlier when I did some dig on Google:

 

https://airbrake.io/blog/http-errors/304-not-modified

 

@Heliohost Teams: delete this if I get it wrong, I’m learning new things.

The page that returns status_code 304 is the correct page for me

I have configured my nodejs application, but I get an error when I request the page to use data from a database.

Please help me. Thank you very much

Creating /home/username/node/tmp/restart.txt works for me, but if it doesn't work for you you'll probably just need to wait 2 hours for the next apache restart.

Thanks you so much

Try renaming or deleting your .htaccess.

 

/home/somedays/beta/ doesn't even exist. Try the guide again. The very first step is

Create a new directory in your home folder named node. Make sure this node directory is NOT in your public_html folder.

 

/home/username/node

 

Username: somedays

please help me

I fixed this error by changing my code to use axios instead of ajax. Thanks everyone

Then why did you use his email address to register your account

Do you have more than 1 account?
