@Pasan Menaka Weerapura - Welcome to Microsoft Q&A and thanks for reaching out.
It's possible that there may be an issue with your eligibility for the Azure student offer.
Please check below on few things before you contact Azure support:
- Make sure that you're signed in to the Azure portal with the same account that you used to apply for the GitHub Student Pack.
- Check the terms and conditions of the Azure student offer to ensure that you meet all the eligibility requirements.
- Try accessing the offer through the link provided in the GitHub Student Pack, rather than through the Azure portal.
If you've already tried these steps and are still receiving the error message, it's possible that there may be an issue with your eligibility. In that case, I would recommend that you contact Azure support for further assistance. Hope this helps. and please feel free to reach out if you have any further questions.
