so when she runs the curl command, where did she get that ip address? is that the public ip address of her instance? if I'm using elastic beanstalk would I use the domain given to run my tests? because when I check my path just by visiting the website that gets served, I get a 200 code but my healthchecks at the same path return 400.

It's not helpful cause what happend if I have fargate task running and in the target group healtcheck I don't know the Health Status Detail?, you must show different cases and how to fix it

Before releasing these videos you need to get a native English speaker to check them. No problem with the content, grammar or syntax but the pronunciation of many words makes this very hard to understand. For something released by an Amazon US office this is unacceptable.

@awssupport 5 месяцев назад

Thank you for the clear and precise feedback. I've shared all your points internally with our Support team. ✅ ^AR

@@awssupport i think accent is neutral , clear and easy to understand especially for non native users, some times there are so many native accent which non native users find difficult to understand and hence quite unacceptable. GOOD WORK :)
