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.

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
