Just change portNo from 5050 to 5432, save file and restart pgAdmin4

On my system Safari is the problem as it was default browser.

To fix, make Chrome your default browser and try relaunching pgadmin4

OR

Manually fix by $ cat ~/.pgAdmin4.5704814747986328352.addr http://127.0.0.1:62631/?key=0ec25e6a-dfe2-483e-9814-b315ea87c3cf

Paste what you get in Chrome

I removed the local directory hidden and resolved:

$ cd ~
$ rm -r .pgadmin/

Note: macOS Sierra (10.12.6) and pgAdmin 4-1.6. Also you are going to loose configuration data like database list tree, et al.

The Databases will remain intact since you are modifying/deleting PgAdmin related data not any of Postgresql itself.

I had the same issue, I fixed it by stopping the service in Postgres app, then start pgAdmin, and then start the Postgres service. I was able to connect it after that. Hope this help.
