API Endpoint not functioning

I'm currently trying my hands at the new JSMastery tutorial which makes use of Appwrite. I ran into an error relating to the validity of the standard API endpoint: "https://cloud.appwrite.io/v1". The error states that the url is invalid and I have been trying to fix it for more than a day now. I was wondering if anyone else had the same issue and if I can get some assistance

TL;DR

Developers facing issues with API Endpoint validity when using Appwrite for a JSMastery tutorial. Double-check project set-up, collections, and environment file. The error may be due to an invalid URL for the standard API endpoint "https://cloud.appwrite.io/v1."
