Question

I am using pgAdmin 4, PostgreSQL 16, Windows 10. Whenever I try to login into pgAdmin for postgres user, I get can Connection TImeout Error.

I tried reinstalling postgreSQL, running pgadmin 4 in adminstration, but still didn't work. I can login in command prompt but not in pgadmin 4. I get connection timeout Error.

Please help me, as I need to learn PostgreSQL with pgAdmin.

Some extra details: My postgresql is in D Drive.

Here is the logs. ==>
