Why won't MicrosoftAjax.js load over SSL in google chrome on some PCs? - ssl

I'm using microsoft's CDN for pulling down the Ajax libraries. And I'm using SSL on some pages.
This URL resolves fine in Firefox and IE:
https://ajax.microsoft.com/ajax/4.0/MicrosoftAjax.js
However in google chrome (on my PC, today...) it seems to time out with a very odd response:
On other PCs it seems to work fine, however I know I'm not the only one experiencing the problem as we've had occasional complaints from some of our clients about certain pages timing out and failing, that seems to point to the same problem.

As per my comment, I experienced the same issue but with Firefox failing and Chrome and IE succeeding.
Restarting the browser and the computer had no affect. Clearing the browser cache did fix the issue. I can only assume there was some kind of corruption in the browser cache.

Playwright - URL is not loading sometimes

when I start the test, the browser is opened but it does not load the URL.
After 10-15 seconds it stopped to load (see screenshot).
I had updated intelliJ, updated playwright to version 1.28.1 (doesn't help)
It happened 7 out of 10 trials.
Any idea why it suddenly becomes that behavior?
Many thanks!
there are 3 probabilities causing this error when hitting the URL:
Your browser version could be a outdated which the site is blocking, so try updating playwright browsers using the command 'npx playwright install'.
Check whether the site is being blocked due to any firewall or proxy setting and if so, get it whitelisted.
As the request also seems to be a crash due to timeout, kindly check whether you have decent internet speed.

SSL_ERROR_NO_CYPHER_OVERLAP - but only on a few select Systems

I encounter the problem when I try to access the website of my software engineering uni course. On my desktop (Win10), phone and tablet (both Android) I receive a "SSL_ERROR_NO_CYPHER_OVERLAP"-Error when trying to access the site.
The error appears regardless of browser, it seems to be system-wide.
Interestingly enough I can access the site on my laptop (Win10 + Manjaro) and could also access it on my desktops Manjaro partition. I could also access it on my phone in the uni-network - but not using mobile data.
However I am not sure, whether mobile data is to blame, as I logged in with my firefox account before receiving the error. Naturally I assumed it may have something to do with my firefox-preferences, but i am using the same account on my Manjaro Systems as well as the Win10 partition of my laptop. Besides me, none of my friends, except one have this problem.
I ran the URL through multiple different SSL-Checkers and every one of them encountered problems regarding the SSL-certificates. As the problem occures in different networks I can also rule out some router-settings of my home-network being the cause. Have you encountered such an error before and is there anything I can do on my own or is this an issue I should take up with my course-instructor and ask him to take a look at his server?
As it turns out the browser plugin "HTTPS Everywhere" was causing the problem.
The error occured in different browsers without the plugin because I copy-pasted the https URL. The issue appeared on my phone because of the shared browser history, which autocompleted the URL to the https version. The plugin is not installed on my Manjaro's Firefox, which is a bit strange as I though it would be shared.
Additionally, on Manjaro, Firefox does not suggest the https version of the site for auto-completion - maybe it favors sites opened on the specific device over sites opened on different devices. Either way, it works now.

Website loading slowly or not loading after clearing browsing history in IE11 Browser

1.Clear IE 11 Browsing history, cookies etc.
2.Close the browser
3.Open the browser
4.Navigate to https://www.parcelforce.com
Expected: The parcelforce.com home page should load properly and quickly in IE11
Actual:
Page does not load properly. Also, on refresh the page takes a lot of time to load. Sometimes it may not load.
This issue is happening with IE11 only. Whenever I hit https://www.parcelforce.com in other browsers say chrome, Firefox, safari, website is loading quickly.
Can anyone suggest me what might be the issue with IE11. Should I need to add any code for IE11 to load website quickly?
Based on your description, I reproduced the problem you described. And I found some other things, when using the address bar and enter key (two or more times) navigation can make the page complete loading. But using ctrl+R or F5 to refresh cannot achieve the same effect. I checked the console in ie11 and did not find any error messages (except warning messages), so I am not sure if it is a compatibility-related issue or other issues in the code.
On the other hand, the Internet Explorer 11 desktop application will be retired and go out of support on June 15, 2022, I recommand that you could use some morden browsers, such as Chromium Edge.

Chrome Headless - Firefox

I'm working on a monitoring tool for my website to log data. The actual logging is made on server. My goal is to calculate stats based on how long the user stays on the website.
Main question: I used chrome headless command --remote-debugging-port=80. I got logs for up to 10 minutes. Works perfectly. But how long will it work if left working? Is there a default timeout? If yes, how can I change it? If I want to run it exactly 30 minutes after page finished loading?
I'm trying to do the same on firefox (tried using PhantomJS but it wasn't loading the page correctly even though useragent was set to firefox) but firefox just throws an bank page when I'm trying to start a headless mode. I used "firefox -headless" and tried capturing an screenshot. It was just exiting my currently open firefox tabs without capturing any image. Any idea?
Using firefox quantum 59.0. I don't want to use selenium.
Also PhantomJS solution would be great. Currently I just want to collect logs. So, it only have to run all javascript (an jquery) code on the page which then sends the data using ajax. I tried page.onLoadFinished and then a wait function to make it stay on the page for the exact time after page loading.
Since no one answered, I will try to answer my own question after even more research and logical thinking.
Main question: Seems that there is no timeout but if need can be used --timeout X. Even though it's not perfect because it runs independently if the page if fully loaded or not.
As for the firefox, it's buggy. -new-instance (make headless run while you are already on firefox) is not working and -no-remote didn't help. Firefox is only working if running only one instance. So, if it's the PC you are working on and you want to run tests too, firefox is not for you. Headless runs only when no other instances of firefox are running, while chrome runs fine.
PhantomJS didn't work even though tried multiple solutions.
Best solution? Use chrome. Need portable? Use chromium and use headless. Or write your soft to use cefsharp which is based on chromium. Your browser with all libs will be around 120-200MB. Pretty big for portable but do it's work. Same as portable chrome or chromium. CefSharp have a privilege of integrating whatever you like into the browser since it's a... browser.

Apache CentOS HTTP Test Page displays - but only for my specific browser

A client's website was working fine, until they had some problems with their web host. Temporarily, the Apache CentOS Test Page was visible. The host claim the problem is fixed - and it seems to be - for everyone but me...
I'm using Safari 7 on OS X Mavericks and every single time when I visit their site I still see the test page.
When anyone else uses their own computer with any browser, it works fine...
When I use Chrome on my Mac it works fine... So the problem is just with Safari.
I've tried clearing Safari's cache
I've tried clearing the DNS cache
I've tried a restart
But I've got no idea why I can't access it. I need to access the site to work on it - yes I can use Chrome, but Safari is my primary browser. Any ideas?
It turned out this was caused by an issue in a Regex within Apache's Mod_Security. The Regex falsely identified a string contained within a cookie as being an SQL injection (it wasn't - purely coincidental).
