The Red Connection Light
Almost 90% of the connection issues students face on our platform have a red connection light at the top right corner of the screen. This is a great indication that something is wrong. So let me help you to understand what are the factors that cause this problem and what you can do to solve the issue!
Factors causing connection issues
- Ad Blocker
- Proxy Server / VPN
- Your Internet Connection
- Your Device
If you are using an Ad Blocking service, please disable it or whitelist our platform. While we don’t have any advertisements, we do use Google Analytics and other services to analyze and optimize our platform. However, Ad Blockers often end up blocking these services and can cause some random side effects including connection issues.
Proxy Server / VPN (Virtual Private Network)
If you are using a corporate network there is a chance that Web Socket connections are blocked because most corporate networks use proxies to filter your internet access. Our platform heavily relies on Web Socket connections to provide you with our learning environment. This type of connection is typically blocked in corporate networks because Web Socket connections are also used for online gaming.
If you are using a corporate network, then please reach out to your IT admin, asking them to whitelist our website. You may have to provide these details to them:
- hostname: app.dataquest.io
- ip: 0.0.0.0
- subnet mask: /0
- protocol: wss
- port: 443
In the case of VPNs, there is a chance that the connection issue is caused by the VPN service provider.
Your Internet Connection
Well, I am pretty sure that many of you have already faced connectivity issues by due to your internet service provider. Sometimes, certain websites are not loading due to their DNS server issues, and other times there are intermittent disconnections. If you are using a mobile network, chances are that due to insufficient signal strength, your internet connection is slow and slow networks don’t work well with Web Sockets. It can also fail due to transparent proxies used by mobile phone operators.
There is a chance that the problem is caused by the device you use. It could be caused by a failing WiFi adapter, browser issues, firewall issues, extensions, etc.
Yep! It might be due to an issue on our end. But there is no way to be sure about that unless you make sure that everything is fine on your end. So let’s discuss that next.
