AWSApprunner not able to send email from django

Question

When I try to send and email from django running on AWSAppRunner instance, the screen stays loading for a while and then it turns all white. If I open my debugger, I see a 502 network error: Origin checking failed {My DOMAIN APPEARED HERE } does not match any trusted origins.

I Forbidden (403) CSRF verification failed. Request aborted. Reason given for failure: Origin checking failed does not match any trusted origins and I added these credentials mentioned in that stack page (CSRF_TRUSTED_ORIGINS,CORS_ORIGIN_WHITELIST, CORS_ALLOWED_ORIGINS, SECURE_PROXY_SSL_HEADER) and then got this error. Origin checking failed - null does not match any trusted origins.

I do have the CSFR token on my html {% csrf_token %}. I know its the email because I comment that send_email function and everything works as expected. I verified the identities (from email and to email) in AWS SES. I installed SES with pip and added :

EMAIL_BACKEND = 'django_ses.SESBackend' AWS_SES_REGION_NAME = 'us-east-2' AWS_SES_REGION_ENDPOINT = 'email.us-east-2.amazonaws.com' I also have my access key, I was able to send the email using my localhost (My own computer running python manage.py runserver). I allowed all trafic in and out on the security group.

What else can I try ?
