Django app to add an instance's public IP to ALLOWED_HOSTS for Elastic Beanstalk's health check system

django-ebhealthcheck's Issues

Invalid HTTP_HOST header: '172.31.31.126'. You may need to add '172.31.31.126' to ALLOWED_HOSTS.

I continue to get this message in /var/log/web.stdout.log log file having added 'ebhealthcheck.apps.EBHealthCheckConfig', to my INSTALLED_APPS.

Invalid header X-aws-ec2-metadata-token (invalid return char or leading space in header)

Hey,

Thanks for the awesome work you've put into this lib!
In our CI (Github actions), we're occasionally getting this error when get_ec2_instance_ip() runs.

requests.exceptions.InvalidHeader: Invalid return character or leading space in header: X-aws-ec2-metadata-token

It happens approximately 1 in 4 times everytime our CI runs. Usually when we face this issue, we just manually run the CI in hope of a metadata-token that won't throw this error, but it's getting a bit tedious. Especially that our CI runs more than once a day.

I'll work on a fix and create a PR now.

requests.exceptions.ReadTimeout

this error came up in local development while using the planes wifi

No issues, Just thankyou.

Hi, this package saved my day. I spent almost two days in this 400. This package is awesome.
