Week 3 Assignment Auto scaling trouble

Good Evening
I have been working on this course for a while and I reach the same area for a fault. This is in step 7. I can not scale done to T3.nano from micro scaling down. The error is “Remove subnet for EC2 Auto Scaling templates”. This has happened 3 times and I followed through with the exercise the third time so as to be familiar wit the exercise. When I submitted I was graded only on the fort to parts and nothing from Auto scaling on wards understandably. How best can I remedy this?

Hello @MoyoKwaLee,
It seems you need to uncheck that box, step 7.1.4. After that you should be able to create the template:

Thank you. This worked. How ever now i have another problem


It say i do not have permission to complete the next tusk.
I then tried the Diagnostics with Amazon.
then got the following error

What do I do?

Hello @MoyoKwaLee,
Could you check you are using the correct instance from the dropdown, t3.nano instead of t2.nano. Thanks
