I am using cloudflare to protect my website recently,but I have a page which is using python socket to send streaming data to visitor with 5000 portsuch as http://mywbesite.com:5000.Before using clouldflare, visitor can get data from port 5000, now after usingcloudflare, all visitors to my website can not get any data from port 5000.Now I pause cloudflare, the python socket port is working back again..The question is I would to like to keep all cloudflare service such as proxy but python socket port need to work for exception by cloudflare, how can I do that ?My Simple python socket code:from flask import Flask, render_template, request, session,jsonifyfrom flask_sse import ssefrom flask_socketio import SocketIO, emit, join_roomimport platformimport loggingfrom flask_cors import CORSimport socket....if __name__ == "__main__": app.run(host="0.0.0.0",debug=False, port=5000, ssl_context=("mycert")

After clicking some Googe Ads and leave the ads site or delete the tab, your browser may forwards you to other site which may give you message such as "Congrulation,! You Get Prize, Bonus, Coupon.etc" Probably your browser is infected by virus and the Congurlation site is hacker /attacker virus site.. I will think the following methods to solve my problem, Please advise those methods are correct 1- Right away or now, remove the forwars site(Congrulation site) or delete such browser Tab 2- Look at this image: https://computer28.com/image/deletecache.jpg Delete or clean your chrome browser data At Chrome browser, Click Sitting->Privacy Security->Delete Browser Data, it will pop up window, in that window, Click Advanced->Select Time Range(All Time)->Tick all box below Time range such as Browsering History..etc. Click Delete Data button 3-If using Window 10, Turn on Microsoft Defender Virus Protection System, always turn it on https://carleton.ca/its/help-centre/how-to-enable-windows-defender-on-personal-pc/ You are better to install Microsoft Window 11 if u are using WIndow 10 4- Add X-Content-Type-Options: nosniff on header at my apache server

Visitors or users may open many page of website to get streaming data ,and they want to open many browser tabs to read different data. That will depend on your Laptop or mobile capiblity how can handle many new socket.io to run on multiple tab at the same time, If limited computer resouce or memory, you will be limited for number of browser tabs display.If u use socket with Redis /stream event that allow display directly into html page tab (just type https://yourdomain:5051/stream on address bar) or throught javascript parse data into html page but it may only allow 3 tabs running on the same time.How you can run it on many tabs ?-----------------------------------------------1-You can use localStorage(getItem or setItem) to share information between browser tabOr...you can use2-window.addEventListener('blur', notstream);window.addEventListener('focus', stream);When the user not read or not focus the tag, close the streaming socketio, then Whenthat users want to read it again and focus the tag, reconnect the socket. We know users only can read 1 tag at a time only,function notstrem(){souce.close();//close the socket.io}function stream(){//user focus the tab againrefresh();// re-run that funation u can stream data before}function refresh(){//Redisvar source = new EventSource("https://yourdomainsocket-site.com"+":5051/stream"); source.addEventListener('publish', function(event) {dataextract(event.data);if (typeof ws=='function')ws(event.data);if (typeof updatechart=='function')updatechart(event.data); }, false); source.addEventListener('error', function(event) { }, false);return source;}let source=null;jQuery(document).ready(function($) {console.log("onload");source=refresh();});

Dear Export,
I've shared-server account in one hosting and now I switch into unmanaged VPS account in
the same hosting company.
So at the shared-server I got one IP and
at VPS acount I got other new IP.
But when I connect ot my website after pay the VPS account, sometimes
it go to VPS'IP correctly, but sometimes, it go to the old IP of shared-server
I reported it to hosting company, they mentioned it might be due to
DNS propagation delay but it is already 4 days long, how DNS propagation is
so long. ANd they reply, you may need to change httpd.conf
So Why my website is not stable. Sometimes, I can see my expected page, sometimes, I
see the old shared-server account , suspend page I mean the old account is suspended
When I try to inconfig/flushdns, but it doesn't help at all
and when I try to ping mysite.com, it report VPS IP bit the content of webpage
is still the old shared-account page. Why
I aks other users to test it at Hong Kong side, all users is getting the same unstable on
my website. At HongKong side, I get unstable webpage, sometimes new VPS page
and sometimes old acount webpage, WHy ?
They just reply me at US side, my website display correct content page and capture image
to let me see. I talked to them. I mean the website is unstable
Please advise

THanks for your reminder

That is a normal timeframe for the DSN to propagate. You should be aware though that the Chinese government does monitor the Internet in Hong Kong. Not as much as mainland perhaps but it's certainly there. I have just returned from both Hong Kong and shanghai and noticed significant delays and timeouts to most sites on multiple private and public networks. When i connected to my vpn i didnt have these issues. Certainly sites such as YouTube are outright blocked in mainland china and not in Hong Kong, though there were significant issues regarding general browsing
Author: duncanb7 replied at 2024-03-22 03:16:33
Thanks for all of your reply
THe root cause is the DNS propagation delay that is almost 48 hours to finish
And there is no any firewall at Hongkong

Have had lot of trouble with DNS issues in China and Hong Kong. I suspect it would be the Chinese firewall not allowing DNS updates as quickly or as you would like. What I'm saying is you may need to wait a lot longer for this to happen

Do you have access to a computer where the problem exists? a dig report from that area would be helpful.
Expert: Michael Munger replied at 2024-03-21 07:07:52
Fly should be TTL. I am on my phone, and auto correct changed it.

Sorry. Not sure what I was thinking. Your FLY values are in seconds. That's just a couple of hours not days.

8524 is the number of minutes for the TTL. it's 5+ days before the DNS will complete propagation. As someone above me said: it's a DNS issue.

.htaccess files are hidden on a server...
(the . prefix makes them "hidden"...)
ls -la
will show them if they are there.
And they are placed in the directory they are supposed to protect/configure.
Also ipconfig/flushdns only flushes your local cacheon you local system, not all intermediate caches with providers.
Try the dig tool (domain information groper)
dig +trace your.domain.name
or
dig +showsearch your.domain.name
should give more info.
These should be done local, not on the server.
You may need to find a dig version for windows, don't know if it is there by default, or even if get installed).

After rebuildhttpd.conf, it is still problem, and I check /usr/local/apache/conf/httpd.conf,
it showed the ip of the VPs which is normal .
But I still not able to have a stable my website connection.
If sometimes my website will go back to my old IP of shared-server acccount,
and I ping it on window , it showed the old of IP.
But at US side, my hosting said they found no problem and report the new VPS' IP address
At HOng Kong side, all of users are aware my website is not stable, sometimes, works, sometmes not,
After reboot and rebuild httpd.conf, it is still in problem, so it might NOt relate to
httpd.conf or apache issue
Or it is related to DNS propagation
Any more suggestion

it sounds much more like DNS than a problem on the VPS
perhaps your DNS hosting company has a DNS server that your updated address has not propagated to ?

DNS works with TTL in the entries on the server.
all intermediate servers (between any client and your DNS) may retain the RR (dns resourse record) for TTL seconds in the cache. [ no need to ask the parent to get an answer.]
If the TTL counter (decremented every second when in cache or at client systems) reached 0 the record drops from the cache.
So it boils down to how long were the original TTL in the RR's.
86400 seconds = 1 day.
Until all caches are cleared from the old records someone may get the wrong answer.
[ you normaly reduce the TTL 10 10 minutes >original TTL seconds before you cut-over
so this unstable period is only a few minites, after succesfull cut-over you restore it to the original TTL ].
Then you may have code in your cgi scripting, redirecting to some hardcoded address.
or in the apache httpd.conf found mostly in (/etc/httpd or /etc/apache) directories.
of some .htaccess file
you need to search your config for it.
