I'm experiencing issues with my Angular (Frontend) and Strapi (Backend) application hosted on a Windows Server using IIS as a reverse proxy. The application sometimes returns a 502 Bad Gateway error instead of the expected 206 Partial Content response.

The flow of events is as follows:
1. A file request is made by the browser (Frontend app).
2. The request is forwarded to the Backend (Strapi) by IIS.
3. A 206 Partial Content response is returned by the Backend.
4. Instead of receiving this response, IIS sends a 502 Bad Gateway error to the client.
5. The browser is forced to retry the same file request.

This issue arises from the fact that IIS, which is primarily designed for hosting .Net applications, is being used with a Node.js application.

I'm looking for an expert who can:
- Diagnose and fix the IIS configuration.
- Tweak request forwarding rules, response handling and proxy settings.
- Potentially help with setting up a more suitable hosting environment if necessary.

You should have extensive experience with IIS configuration, as well as a good understanding of Node.js applications. Please apply if you are confident in your ability to resolve this issue.

Skills: Software Architecture, IIS, Azure, Windows Server, Node.js

Hello everyone,

I got a Node script which is used to get a m3u8 link from a website page.

The script is using Puppeteer to load a web page which has PlayerJS on it and then it listens to a m3u8 link which is delayed and coming in about 1 - 2 seconds.

The script is small and working perfectly. I will provide the script once the proposal is accepted.

BUT: the PlayerJS always loads with 360p preset quality in it (see 360p_by_default screen attached) which is bad. When we choose better quality in a real browser - a new m3u8 link is coming in in about a second (see 1080p_selected screen). The total qualities list in the player is different, but the most full list is (see all_qualities screen):

1080p Ultra
1080p
720p
480p
360p

Sometimes the page can only have 2 - 3 quality options, but sometimes it could have the full list as shown above.

I need the script to be updated and do the following:
Load the given URL and ignore the first coming m3u8 link (already done)
Parse the list qualities and initiate a click event on the best quality option like we do it in a real browser but in the case of script we should use Puppeteer (or any other library you like) to do so.
Listen to the next coming m3u8 link which corresponds to the better selected quality.

Please note that this script will be used on MacOS. It actually doesn’t matter which OS is used but would be great if you could test it on MacOS.

If you require the Puppeteer to launch the external browser in order to accomplish the task - that is fine, but the script should do the job.

IMPORTANT: You can even write your own script on any other language, we don’t care, we just need a console based script that will do the job, preferably in MacOS.

Looking forward to getting assistance with this.

Regards

Feature: "Life Journey Evolution"
Dynamic Traits: Each NFT changes over time, reflecting its "life story." For example:\n - After a certain period (e.g., 1 month), the pup grows accessories like a collar or a toy.\n - Owners can unlock new animations by participating in specific actions (e.g., donating to shelters, completing community challenges).\n - Unique backgrounds could evolve, like moving from a simple yard to a magical forest or beach based on user interaction.\n\n- Gamification: Introduce small quests or events, such as:\n - Voting for shelters to receive donations.\n - Sharing rescue stories on social media to "rescue".\n\n- Emotional Bond: The evolving nature of the NFT creates a deeper emotional connection, as owners feel like they’re "raising".\n\n- Dynamic Metadata: Utilize blockchain-based dynamic metadata updates (e.g., Chainlink oracles) to reflect these changes while maintaining NFT authenticity.\n\nThis feature would make the NFTs more than static collectibles—they become living, interactive companions, driving engagement and emotional investment, and setting the collection apart in the NFT space. Would you like help planning the technical implementation for this feature?
