Problems trying to connect to local database with pgadmin4

I am new with backend and postgresql. I am trying to to set up on linux mint.

I have installed postgresql.

And set up pgadmin4 with python as instructed https://www.pgadmin.org/download/pgadmin-4-python/

After connecting to pgadmin4 and going to the local address with browser and logging in with proper username and password I get error message in terminal as follows

The pgamin opens browser and there is one "Server" but nothing inside it.
(Not sure if this helps with anything but if I try to create new servers they are empty)

How can I address this? Or can you recommend better alternatives to pgadmin for linux mint?

The error message you received indicates a timeout while checking for updates in pgAdmin. This error should not affect the functionality of pgAdmin or your PostgreSQL database. Here are some steps to address the issue:

*Disable automatic update checks in the pgAdmin configuration file.
*Check your network connectivity to ensure a stable internet connection.
*Try using a different browser to access pgAdmin's web interface.
*Verify the connection to your PostgreSQL server in pgAdmin.

If the issue persists, you can try alternative PostgreSQL administration tools like DBeaver or Adminer. Another option is to use the command-line tool called psql.

Remember, the timeout error should not significantly impact your ability to work with PostgreSQL. You can try the steps mentioned or explore alternative tools based on your preference.
