PgAdmin Server Errors
PostgreSQL and High Sierra Issues
Possible Causes of Server Contact Errors
Users of PostgreSQL who are encountering the "PgAdmin 4 server could not be contacted" error may be experiencing issues due to several potential causes. Firstly, if you are a new user of PostgreSQL, this error may indicate that you have not yet configured the pgAdmin 4 server. Additionally, if you have recently upgraded to macOS High Sierra, you may find that the latest version of pgAdmin (4.20) continues to display the error message "Application Server." It is important to note that there are multiple possible causes for this error, including:
- Incorrect configuration of the pgAdmin 4 server
- Compatibility issues with macOS High Sierra and pgAdmin 4.20
- Firewall settings blocking the connection to the pgAdmin 4 server
- Network issues preventing communication between the client and the server
