Everything was working fine, until suddenly my docker-compose up & manage.py migrate & manage.py makemigrations all started failing.
an example is below.
C:\Users\tgmjack\Desktop\londonappdevelopersexample\my_ec2_ting\app>python manage.py makemigrations
C:\Users\tgmjack\AppData\Local\Programs\Python\Python310\lib\site-packages\django\core\management\commands\makemigrations.py:143: RuntimeWarning: Got an error checking a consistent migration history performed for database connection ‘default’: connection to server at “localhost” (::1), port 5432 failed: Connection refused (0x0000274D/10061)
Is the server running on that host and accepting TCP/IP connections?

warnings.warn(
No changes detected
Since the error complained of inconsistent migration history, i deleted my migrations folder thinking i could just start again. That changed nothing, so then i decided to delete all my previous containers and images in docker too.
The postgresql server is now running again after doing another docker build. but it still doesnt want to connect.
below is the last bunch of lines from the logs of my postgresql server copied from inside docker desktop. I believe this shows that im doing things right (ie my server is running on 0.0.0.0:5432)

Success. You can now start the database server using:

weirdly enough i cant find anywhere in my dockerfile or settings.py etc… where the number 5432 appears.
why can i not connect to the postresql database?
