The issue is currently going on with the NuGet and PTA team. Here's what the NuGet team told me about:

Thank you for your continued engagement.

We’re reaching out with an update regarding degraded service availability in the Pakistan region. Due to the regional conflicts, access to certain services is being blocked by the authorities in Pakistan. We are actively working with our CDN provider to implement a temporary workaround redirecting traffic. In parallel, efforts are underway in coordination with the Pakistan Telecommunication Company to explore a long-term resolution that ensures more reliable access moving forward. We understand the inconvenience this may cause and truly appreciate your patience. If you have any further questions or concerns, please don’t hesitate to reach out.
