The first loading for a site shows a connection refuse error.
This site can’t be reached
Xyz.com refused to connect.
Try:
• Checking the connection
• Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
Then, when I refreshed the site, the site is up and running.
The tech stack for the site is on
Django
NginX
Gunicorn
AWS Ubuntu v18.
This is a bit unusal, where can I start off to check the connection?
I've tested a web socket project which uses tomcat7 on localhost and it works perfectly. I've deployed it into digital ocean server as well and it works perfectly. However when I tried to deploy it to AWS bitnami EC2 instance, it returned a "failed: Error during WebSocket handshake: Unexpected response code: 500".
I would really appreciate it if a solution could be given or a step-by-step process to fix this. Currently there is no solution to be found on the web and I believe many people are facing this issue as well.
I was working on django and everthing was working fine on my local machine as well as on heroku.
But than i deodorize my django project and it was working fine locally till now. now i have depolyed this container on my dedicated server and than i came to know that my emails was failing after deployment.
Can anybody have idea why my dedicated server is not sending mails?
I am sending mails using smtp protocol.
Any help or suggestion will be highly appreciated.
Thanks.
I'm assuming you're connecting to your local SMTP server to send out those emails.
The problem is that your Django is trying to use localhost:25 to send out the emails and in your docker there's no SMTP server. Docker has it's own network, and you can see what are the interfaces available by executing
ifconfig
To solve your issue, you should tell django to use your host SMTP server (and not localhost). Moreover you should tell your local SMTP server to accept emails coming from the docker network.
I'm trying to deploy a parse application according to this document https://aws.amazon.com/it/blogs/mobile/how-to-set-up-parse-server-on-aws-using-aws-elastic-beanstalk/ .
I deployed the application in aws, created a mongolab cluster, copied the connection string in the environment panel and started the application.
If I try to test using curl according the aws tutorial I receive an interval server error.
How can I understand what's the problem?
I'm pretty new in WS programming.
I created WS (that I picked the base from http://www.digicoast.com/delphi_soap_standalone.html) using delphi-7
When I consumed it through XAMPP php nusoap that is installed to my PC, it worked well and I got the requested result.
But when I consumed it through php nusoap on my web hosting, it returned nothing.
When I put debug in the php codes, it says: HTTP Error: Couldn't open socket connection to server. Error(110): Connection timed out.
Here is my php codes:
<?php
require_once('../lib/nusoap.php');
$aparams = 'kode_query='.'TRIPS_ALL'.'&'.
'kode_user='.$username.'&'.
'kode_id='.$uid;
$client = new nuSoap_Client('http://110.139.181.78:9696/wsdl/IVSoftWS');
$xml_data = $client->call('GetXMLDataTable',$aparams);
echo '<h2>Debug</h2>';
echo '<pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';
echo '<h2>Error</h2>';
echo '<pre>' . htmlspecialchars($client->getError(), ENT_QUOTES) . '</pre>';
?>
Info: my web hosting using php 5.2.9, while my XAMPP using php 5.3.1
Question: How can I get the same result through web hosting php codes?
Any helps are really appreciated.
Have you checked the firewall settings? The server seems to run on port 9696, this port needs to be opened on the server (more precise: the server which runs the Delphi 7 web service server app) for incoming connections.
To verify, you can use a web browser (or wget) from a different computer, and try to open the service URL.
