Problem connecting to Dockerdb in pgadmin

Hi every one
I create a web app with Django, Postgresql and docker when i run the docker file with docker-compose up it connects to db (with given cridetnials defiend in Django) and i can add records to tables and so on but when i want to open that db in pgadmin4 it throws this error pgadmin4 error any idea where the problem is p.s : i defined a PGP for my docker image and any time i run docker desktop i should enter the password to connect to


I search internet but could not find a useful solution
