Web.dev shows that there are console errors from third party tracking software (LuckyOrange):
WebSocket connection failed: Error in connection establishment:
net::ERR_NAME_NOT_RESOLVED.
Tried to reproduce same error with Lighthouse in Chrome DevTools, also with Lighthouse CLI, Headless Chrome. Was unable to do that. There are no errors in browser console too.
Maybe somebody have experienced the same issue?
I have experience with this. I have always ignored these warnings as they are inconsistent. I THINK they are caused by my CDN blocking the automated requests, resulting in console errors. For me it happens every now and then and only after repeated querying.
Note that I have no proof for this theory.

I have a domain x.com which is running a web application
There is an MQTT server running on subdomain mqtt.x.com, with websockets / wss all set up,
Using Chrome:
If I head to https://x.com, and run this in console:
let ws = new WebSocket('wss://mqtt.x.com')
I get the following error:
WebSocket connection to 'wss://mqtt.x.com/' failed:
If I go to a completeley different domain (such as stackoverflow.com) and run the command, it works fine.
In firefox/opera/edge, no errors, and it all works fine.
Is there any way to get a more verbose error from chrome?
Or any other idea to resolve this?
Edit
Clearing cookies seemed to solve this. still not really sure why.
Clearing Cookies seemed to be the answer.
I uploaded my Laravel project to infinityfree.net, but get this error:
This page isn’t working right now sitename.epizy.com can't currently handle this request.
HTTP ERROR 500
How to fix this?
The 500 Internal Server Error is a very general HTTP status code that means something has gone wrong on the web site's server but the server could not be more specific on what the exact problem is.
Retry the web page by clicking the refresh/reload button or trying the URL from the address bar again. Even though the 500 Internal Server Error is reporting a general error on the web site's servers and not your computer, the server error may only be temporary. Trying the page again will often be successful.
Come back later. The 500 Internal Server Error message is one of the most common error message seen when checking out during an online purchase so sales are often disrupted. This is usually a great incentive to resolve the issue very quickly.
3.Try Clearing your cache and browser history. It could be possible that the page you are seeing is a cached version, so after the cache is cleared it will go away.
You can check the error log button in cPanel under the logs section to see what errors are being given if you have cPanel hosting with us. Sometimes 500 errors can be due to syntax errors in a .htaccess file or other things you may be able to quickly fix yourself.
You need to "error mood" on in php config file(you can search it in cpanel).error mood off to error mood on to see error log.after you checked the error and solved it change error mood setting.(error mood on to error mood off).I hope this will help you a little.
Some users have been reporting connection errors with Chrome after implementing reCaptcha. The issue appears to be intermittent and when we check the affected user's browser, we found "net::ERR_QUIC_PROTOCOL_ERROR"
Disabling quic protocol on Chrome resolves it but as developers, does anyone know how we can resolve this without requesting every visitor to disable Quic?
Using the Redux Dev Tools extension, I am receiving errors when exporting any time after I have interacted with my app. If I do a fresh page load and export, it works, but after one or sometimes a couple of state changes, I receive "Failed: Network error" from Chrome instead of a download.
Has anyone ran into this issue before?
Your state(s) size is probably too big. I started cleanup unused data from state, and Export stopped failing.
Try also "Commit" to view/get only the last state.

When I click No, I got following error page.
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.
Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.
I also checked the eventvwr log and it says:
**aspnet_wp.exe (PID: 3584) stopped unexpectedly.

Please help me.
I can't see your image (hotlinking to that site isn't allowed), but I'm guessing that when you hit "No", you're telling ASP.NET that you don't want to debug the exception, so it's letting it bubble up to the browser, which shows you the "Webserver unavailable" that you're seeing. If you debug your error, what do you get?
Also, please fix your image so we can see your dialog box.
