Connection Faults

Linux now running, though its acting like its on a 10Mb/sec LAN from 1998.

The only ISP available in this area is Google. MediaCom and CenturyLink refuse to wire up the area.

I suppose I could grab StarLink.

Much faster response times..!! But, still getting awkward banners..

@Martin_Stahl -- the connectivity with chess.com comes in waves.. sometimes decent, other times, slow as kids getting in the car to go to the dentist.

The HTML disconnects are random and hold up functions from performing -- particularly the non-text, non-simple functions. I would not be surprised if Google Fiber is throttling data blocks and causing the issue. I would not be surprised if CloudFlare is doing something similar as well.
I have three methods to connect to chess.com now; App on the Android (and that has its moments as well .. again, possibly Google Fiber throttling customers), Windoze 11 Laptop, and a CentOS Linux PC. I primarily use Mozilla, but I don't think this is a browser issue.

I took the Linux PC off the wifi (it has a shady connection spot). Hooked it up to a 2.5G LAN inside the home.

It, too, is also having spasms of Red Banners displaying "[unavailable] HTTP 502 x" . (On pleasedontblockchess.com )

There's something between my house and chess.com that is just chopping up the data blocks.

Hand-typing in the URLs, I can get better responses. (i.e., I am typing in this comment on the Linux PC -- cannot get to this Club via the menu-bar)

One other thing to try Private browsing and see if that improves anything

@Martin_Stahl -- I have found and fixed the SSL errors. I think this is ~60-70% of my issue.

On Windoze.. post-auto-update of the stuuuuuupid O.S., I went into the internals of Mozilla to undo what I think the auto-update does without consideration---mucks with the MAC addresses.

Within Mozilla Firefox -->

1. Open new tab.
2. Enter "about:config" --> "Accept the Risk and Continue"
3. In the Search bar, enter "security.tls.enable_0rtt_data" make sure it is set to FALSE.
4. Delete all historical data with "about: preferences#privacy" (<-- no space between the : and the p for preferences, most browsers combine that to make the emoji) . Go to Cookies and Site Data, click on Clear Browsing Data. Only check and Clear "Temporary cached files and pages".
5. REBOOT WINDOZE.

Everything should be fine now. You don't need to delete Cookies or Site data or anything else. Just the Temporary garbage that is causing Mozilla to find out that SSL tickets don't match anymore. For the sites that matter.

I still don't know about the random banners I was seeing, but I will continue to monitor to see if/when/how often they appear and if there's a correlation to the App on the Android.

Yes. This also fixes the banner issue for Mozilla on Linux as well.

• Open new tab.
• Enter "about:config" --> "Accept the Risk and Continue"
• In the Search bar, enter "security.tls.enable_0rtt_data" make sure it is set to FALSE.
• Delete all Temporary cached files and pages.
• Reboot ( or in a terminal, type -- "sync; sync; init 6" )

Hung 502 HTML banners are gone.

Thanks for the update.

Update. Happened again with the laptop, went traveling the past few days. Came home and the laptop was not loading anything on chess.com.

This time I went so far as to delete the chess.com cookies from the browser history. Until I did that, the browser kept trying to reference a funky AI site: "https://privacyportal.onetrust.com"

I have no idea why it was stuck there. And chess.com was the ONLY site I could not get to from this laptop, this browser.

After removing the browser's cookies for chess.com, suddenly, it was able to find chess.com without a problem.
---------------why? What is it about chess.com in particular that foments these connection issues?

Is that a personal system? Or work related? It sounds like security software on your system that doesn't play nicely with the site and/or how the site works with the CDN being used.

I haven't ever experienced similar issues when traveling, but I also don't have any software that could interfere.

Brave, don't normally use, works fine.

Mozilla, usually use with the laptop, is getting stuck recently.

I would think a hacker would scan all browser traffic, not just a specific one, and only introduce a Man-In-The-Middle attack on chess.com -- of all possibilities. Wouldn't you rather intercede with bank account transfers?

I have never seen a redirection before to whatever this OneTrust AI workkflow system is.

OneTrust looks to be some kind of corporate auditing and risk management tool.

Yeah. and why would Mozilla redirect there when I enter "www.chess.com" ?? (Until I deleted the chess.com cookies from Firefox.) I've never been to that site before.

Within the Mozilla support site, we have this nugget:

OneTrust is the platform used by Mozilla to manage personal data requests

(source: https://support.mozilla.org/ca/questions/1428069#answer-1612258) except, this is in reference to an email issue, not trying to use chess.com.

It might be associated with something on site. I'm asking about it

It is very likely do to Global Privacy Control (GPC) on Firefox and probably Brave, where there's a network hiccup of some type that prevents that from correctly validating some code the site is using, so the browser will fail to load everything. One possible solution would be to disable that setting and see if the problems go away on site.

Thank you for the follow-up. It seems to correlate with this Firefox setting, then -- security.tls.enable_0rtt_data . It's on by default in Mozilla Firefox and seems to be the culprit, when certain data sets are sent across. 
I would likely NOT be the only one on chess.com suffering from this issue.
