Reason behind error524 connection timeout.
How to fix it even though the website havent cover high storage
Server origin that is being used is from India.

pause the running website then again enable to run the website via cloudflare
.
Error 524 is usually related to a connection timeout issue between Cloudflare and the origin server. This means that Cloudflare was unable to establish a connection with the origin server in a timely manner.
It's hard to tell what is the issue without debugging the server, but I would start by checking the firewall and network settings.
In documentation of Cloudflare, they say that you can change value of timeOut but only accounts Entreprice

Is it possible to increase CloudFlare's time-out? If yes, how?
My code takes a while to execute and I wasn't planning on Ajaxifying it the coming days.
No, CloudFlare only offers that kind of customisation on Enterprise plans.
CloudFlare will time out if it fails to establish a HTTP handshake after 15 seconds.
CloudFlare will also wait 100 seconds for a HTTP response from your server before you will see a 524 timeout error.
Other than this there can be timeouts on your origin web server.
It sounds like you need Inter-Process Communication. HTTP should not be used a mechanism for performing blocking tasks without sending responses, these kind of activities should instead be abstracted away to a non-HTTP service on the server. By using RabbitMQ (or any other MQ) you can then pass messages from the HTTP element of your server over to the processing service on your webserver.
I was in communication with Cloudflare about the same issue, and also with the technical support of RabbitMQ.
RabbitMQ suggested using Web Stomp which relies on Web Sockets. However Cloudflare suggested...
Websockets would create a persistent connection through Cloudflare and
there's no timeout as such, but the best way of resolving this would
be just to process the request in the background and respond asynchronously, and serve a 'Loading...' page or similar, rather than having the user to wait for 100 seconds. That would also give a better user experience to the user as well
UPDATE:
For completeness, I will also record here that
I also asked CloudFlare about running the report via a subdomain and "grey-clouding" it and they replied as follows:
I will suggest to verify on why it takes more than 100 seconds for the
reports. Disabling Cloudflare on the sub-domain, allow attackers to
know about your origin IP and attackers will be attacking directly
bypassing Cloudflare.
FURTHER UPDATE
I finally solved this problem by running the report using a thread and using AJAX to "poll" whether the report had been created. See Bypassing CloudFlare's time-out of 100 seconds
Cloudflare doesn't trigger 504 errors on timeout
504 is a timeout triggered by your server - nothing to do with Cloudflare.
524 is a timeout triggered by Cloudflare.

524 error? There is a workaround:
As #mjsa mentioned, Cloudflare only offers timeout settings to Enterprise clients, which is not an option for most people.
However, you can disable Cloudflare proxing for that specific (sub)domain by turning the orange cloud into grey:
Before:
After:
Note: it will disable extra functionalities for that specific (sub)domain, including IP masking and SSL certificates.
As Cloudflare state in their documentation:
If you regularly run HTTP requests that take over 100 seconds to
complete (for example large data exports), consider moving those
long-running processes to a subdomain that is not proxied by
Cloudflare. That subdomain would have the orange cloud icon toggled to
grey in the Cloudflare DNS Settings . Note that you cannot use a Page
Rule to circumvent Error 524.
I know that it cannot be treated like a solution but there is a 2 ways of avoiding this.
1) Since this timeout is often related to long time generating of something, this type of works can be done through crontab or if You have access to SSH you can run a PHP command directly to execute. In this case connection is not served through Cloudflare so it goes as long as your configuration allows it to run. Check it on Google how to run scripts from command line or how to determine them in crontab by using /usr/bin/php /direct/path/to/file.php
2) You can create subdomain that is not added to cloudlflare and move Your script there and run them directly through URL, Ajax call or whatever.
There is a good answer on Cloudflare community forums about this:
If you need to have scripts that run for longer than around 100 seconds without returning any data to the browser, you can’t run these through Cloudflare. There are a couple of options: Run the scripts via a grey-clouded subdomain or change the script so that it kicks off a long-running background process and quickly returns a status which the browser can poll until the background process has completed, at which point the full response can be returned. This is the way most people do this type of action as keeping HTTP connections open for a long time is unreliable and can be very taxing also.
This topic on Stackoverflow is high in SERPs so I decided to write down this answer for those who will find it usefull.
https://support.cloudflare.com/hc/en-us/articles/115003011431-Troubleshooting-Cloudflare-5XX-errors#502504error
Cloudflare 524 error results from a web page taking more than 100 seconds to completely respond.
This can be overridden to (up to) 600 seconds ... if you change to "Enterprise" Cloudflare account. The cost of Enterprise is roughtly $40k per year (annual contract required).
If you are getting your results with curl, you could use the resolve option to directly access your IP, not using the Cloudflare proxy IP:
For example:
curl --max-time 120 -s -k --resolve lifeboat.com:443:127.0.0.1 -L https://lifeboat.com/blog/feed
The simplest way to do this is to increase your proxy waiting timeout.
If you are using Nginx for instance you can simply add this line in your /etc/nginx/sites-availables/your_domain:
location / {
...
proxy_read_timeout 600s; # this increases it by 10mins; feel free to change as you see fit with your needs.
...
}
If the issue persists, make sure you use let's encrypt to secure your server alongside Nginx and then disable the orange cloud on that specific subdomain on Cloudflare.
Here are some resources you can check to help do that

So, I'm supporting in a WCF that is having some interesting problems. In the application log file, it has appeared the following error:
There was no channel actively listening at 'http://hostanme.domain/Integration/IntegrationService.svc'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening.
The case is that the application is configured to receive only requests in HTTPS, and if some external requests come with HTTP, it responds with a "404 Not Found". The point is that the error request up always comes HTTP and the hostname of the machine in the URL domain. We contemplated a lot here in the office whether it would be if the application calls this URL after the IIS recylce, but we are still on this question, and we can not repeat this error.
Has anyone had a similar situation , or know how to solve this case?
try to run this command :
%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i
When i trying to use my WCF client a get an error
RUNTIME0013: Failed to connect to 'http://localhost:8080....
So if client just cann't to connect to remote endpoint than error looks like
There was no endpoint listening at
But what is RUNTIME0013 ? I cann't even google this kind of error.
I'm using Jmeter to load test my web application. I have two web servers and we are using HAProxy for load balance. All my tests are running fine and configured correctly. I have three jmeter remote clients so I can run my tests distributed. The problem I'm facing is that ALL my jmeter requests are only being processed by one of the web servers. For some reason it's not balancing and I'm having many time outs, and huge response times. I've looked around a lot for a way to make these requests being balanced, but I'm having no luck so far. Does anyone know what can be the cause of this behavior? Please let me know if you need to know anything about my environment first and I will provide the answers.
Check your haproxy configuration:
What is it's load balancing policy, if not round-robin is it based on ip source or some other info that might be common to your 3 remote servers?
Are you sure load balancing is working right? Try testing with browser first, if you can add some information about the web server in response to debug.
Check your test plan:
Are you sure you don't have somewhere in your requests a sessionid that is hardcoded?
How many threads did you configure?
In your Jmeter script by default the HTTP Request "Use KeepAlive" header option is checked.
Keep-Alive is a header that maintains a persistent connection between
client and server, preventing a connection from breaking
intermittently. Also known as HTTP keep-alive, it can be defined as a
method to allow the same TCP connection for HTTP communication instead
of opening a new connection for each new request.
This may cause all requests to go to the same server. Just uncheck the option and save, stop your script and re-run.
