Let's start off by saying what serving the pages with these headers means.

If you have ever built an API with Express.js for example, you'll be familiar with this. Essentially, it means that when the user makes a GET request to see the web page, you will have to send some additional information in the form of HTTP headers.

Specifically, the first header prevents your page from loading any cross-origin resources that don't explicitly grant permission. The second one means that you can't share a browsing context group with any cross-origin documents. Both of these are used as safety measures to prevent cross-origin attacks. Even though you may not be requesting anything, you have to apply them.

Now onto your problem, I would recommend installing the Chrome extension CORS. I don't know exactly how it works, but I have used it in the past and it will be a temporary solution. I skimmed through the tutorial you're following and I didn't see a server setup (as in Express.js/Node's http for instance). If you had any of these you could pass the headers as arguments to the servers.

To check if the CORS settings are working as intended, add the following code to your app:

According to this answer on the LetsEncrypt discussion board, it's not possible to use Certbot/certbot-auto at all with Ubuntu 14.04 anymore (likely because Certbot tries to update itself, and is no longer able to on Ubuntu 14.04).

acme.sh is a different LetsEncrypt client that possibly works.

This is possible in firefox and Safari, window.opener can be current window when you add target _self. If you do window.open('someurl', '_self') then window.opener will be current window and will open in same tab instead of a new tab. This only happens in safari and firefox(from what i have observed). All chromium based browsers don't change the original window opener in any case.

I don't know the exact reason why safari and firefox handles it this way I tried to find the reason but can't find it.

I faced this issue once and the solution which we did was to ask website C to use either window.location.replace or window.location.href to redirect back to website B so they open website b in same tab.

If you haven't already, install Git on your PC: https://git-scm.com/download/win

Then open the command window as admin and install this patch:

Peter Beverloo made an extensive list of Chromium command line switches on his blog a while back.

There are lots of command lines which can be used with the Google Chrome browser. Some change behavior of features, others are for debugging or experimenting. This page lists the available switches including their conditions and descriptions. Last automated update occurred on 2020-08-12.

• See @ https://peter.sh/experiments/chromium-command-line-switches/

If you're looking a specific command it will be there, give it a shot. Tho I'm pretty sure cross-origin restrictions were implemented specifically to prevent what you're trying to do.

Okay I've solved the same problem. Seems if you send a request with cookie to the Instagram's API, it will return 403 back. In iOS, URLRequest by default will add some cookies by the system, which causes this 403 problem.

What you need to do is add:

nestedExpr and infixNotation are not really appropriate for this project. nestedExpr is generally a short-cut expression for stuff you don't really want to go into details parsing, you just want to detect and step over some chunk of text that happens to have some nesting in opening and closing punctuation. infixNotation is intended for parsing expressions with unary and binary operators, usually some kind of arithmetic. You might be able to treat the punctuation in your grammar as operators, but it is a stretch, and definitely doing things the hard way.

For your project, you will really need to define the different elements, and it will be a recursive grammar (since the array and struct types will themselves be defined in terms of other types, which could also be arrays or structs).

I took a stab at a BNF, for a subset of your grammar using scalar types int, float, boolean, and string, and compound types array and struct, with just the '<' and '>' nesting punctuation. An array will take a single type argument, to define the type of the elements in the array. A struct will take one or more struct fields, where each field is an identifier:type pair.

From Python3.10, OpenSSL 1.1.1 or newer is required.

I have tried changing some of your code like below and worked.

delete: openssl-devel

add: openssl11 openssl11-devel.

The answer, thanks to @Tobe E's suggestion, related to versions of Selenium. My requirements.txt file contained selenium==3.0.2, whereas my local installation contained selenium==3.141.0. After upgrading Selenium package and redeploying to AWS, the code worked as expected without SSL Certificate errors.
