Market data connection lost

Thanks to all TRADERS in here,

First of all I would like to thank you all for the input. I will certainly look into all your advice/tips. Unfortunately, I am not a computer wizz. I am better at Trading/scalping :), but for that everything has to run accordingly.

Some more info:

The thing is, I have this same problem when I was in Asia for 1/2year, with a NEW build pc, AMD Ryzen 7 3700X, Corsair DDR4 Vengeance LPX 2x16GB 3200, Samsung 970 EVO 1TB M.2 SSD.....(Nov 2019), so I don't think it could be the PC. The pc I am using now, is almost similar to the one mentioned above, just as fast but a year older.

My connection, is hard wired, NO Wifi, I have a margin account, with live datafeed for all US instruments, so NO paper account. The internet is Download ~255 Mb/s, Upload ~26 Mb/s, Ping ~18ms.

No other software running beside TWSlatest/Beta/Stable. NO VIRUS software (since I don't do anything else on this pc), Firewall ON but I don't think is the issue, cause the issue mostly/only occurs, during US RTH and that is around 15:30-22:30 CET (09:30-16:30 US Easter Time).
My region setting is Europe, but my time setting is US ET (NewYork time), for right time in my charts.

One thing I found out is that my pc, somehow cannot open the Interactivebrokers.com website. After clearing all history in Chrome, I will be able to open the website only once, but the second time, I see "Site is unavailable". Interactivebrokers.co.uk is not a problem. ANYONE have any idea about this issue?

When problem still persists, after completely new installation of Windows, on my harddisk I still have a few options.

-I am considering Glassfiber connection, but it takes about 2 weeks to have that all set up, without any guarantees.
-Second/NEW PC
-Another broker, which will be my last resort :((, since I think IB is the best by lack for any better. (I trade futures, Options, but because of this issue, I am forced to trade stocks only, because with stocks, not every second delay is deadly)

Reading all your tips, I have to conclude that i am the only one with bad luck :(, I can not, and WILL NOT accept this issue, how frustating it might be to solve.

Once again, MANY THANKS for the input so far, and I do appreciate any further suggestions or tips.

Phuong_rdam@yahoo.com for any tips or suggestions / or pm is also ok. THANKS

You are focusing too much on your computer and the components it is built of. None of us had put any blame on that. It is not your computer. You should be looking into your connection to the internet. Your router. Your ISP, etc. Your remark about not being able to get to IB's website is already a good indication that something is not okay with your internet connection.
 
Hobby is correct. That not connecting to a web site is a good clue. Not a TWS issue. I would look at all the network hardware and settings. Try using wireless. That will drive a wedge between the network hardware on your machine. If no difference, then move onto your router. There are a lot of setting there than can mess things up.

Once I had a couple of simple problems: It was the actual cable. One was picking up interference from an old style CRT. The other was the cable had a crimp, and another was the plug crimp was bad, another time the socket in the wall was messed up. The point is this is solvable.

Also, you can connect wirelessly to your cell phone hot spot. Try that. That is a different "ISP". Of course don't trade.
 
Sounds like a MTU misconfiguration issue in your router (or at your ISP).
Dropouts are more than likely a packet loss issue (which could also be MTU related).

Try doing speedtests to other destinations (speedtest.net) - your ISP may be lacking in upstream bandwidth.

There are no problems, only solutions.

Try opening the site in an incognitio window. Do you have the same issue?
 
I have this alert everyday approximate same times each day. For me it occurs between 1130 -1200 CST. I have checked connections on other computers at the same time I have gotten these and all seems good on that end. My data feed doesn't stop, or appears not to stop, but I get the disconnect warning. Today I have been getting late fill notices with no alerts that there is an issue. One was roughly 15 seconds before it showed the trade even though I watched it trade through by multiple ticks.
 
Dear Traders,

Before going into detail, once again, my thanks to all you people out there, helping me solving this problem.

Result of a completely new windows 10 installation on a blank SSD harddisk is still the same. Still "Market data connection lost" and a second later "Market data connection reastablished". So it is not my computer, firewall or anything from my computer. Also the issue of second attempt to open up www.interactivebrokers.com still gives me "This site can't be reached"

Taking your advice, it must be my ISP, so I ordered glassfiber this morning. Next week oct 15, I will have it installed. I will keep you people updated. I am sad but somehow I am also glad that the issue might be solved, when I have another ISP with glassfiber. At least I have done all I can from my side.

Thank you all so much for your time, effort and thinking.

Regards,

Dear Traders,

I just tested with my phone connected with WIFI, and my laptop connected with WIFI, both have the same issue, when I try visit the site www.interactivebrokers.com the second time. So it must be my ISP, I am really thankful for all your help and input. Update will follow.

That says it is not your ISP. It is your setup. Any other machines available? Did you sign up for a paper account? Paper uses as different connection to IB. I am not sure about the IB web site issue. I would set that aside for now. Setup the paper account and try that. Also there should be a log on TWS you should be able to check.

Are you using the same ISP for both your phone and your home connection? It would be unlikely that 2 different ISPs would result in exactly the same problem.
Are you using a VPN?

I think a better test is to use a 4G phone connected with a USB cable to the laptop. On an Android smart phone, select:
Parameters->Connection->Mobile Hotspot and Modem->USB Modem
