Hi,

I'd recommend looking for other errors in your DSpace logs and/or Tomcat logs.  The error you shared is *usually* a side-effect of a different error.  It's possible that Tomcat isn't running, or has failed to start up properly.  See our troubleshooting guide for more information about looking for errors in logs.  https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

Feel free to share what you find on this list or the Tech Support list at dspac...@googlegroups.com.   Keep in mind, it's also very useful to share which version of DSpace you are using, as that can help others to provide you with more accurate advice.

Hello Precious,

I trust this message finds you well. I would like to address the error message that you have shared concerning the unresponsiveness of your DSpace site. The error logs you provided indicate several issues that might be contributing to the problem. Let's explore these aspects further in order to pinpoint the cause and determine an appropriate solution.

1. WebApp Connectivity Error: The critical error message you highlighted suggests that there is a connectivity issue with a running webapp. The error is a "java.net.ConnectException: Connection refused" error, which means that the application is unable to establish a connection to /dspace/webapps . This could be due to a permission or network or configuration issue.
2. Network or Configuration Issues: The error points to a connection problem, specifically during an attempt to establish an SSL/TLS connection. This could indicate a network issue, firewall restrictions, or misconfigured SSL settings.
3. Database and Hibernate Information: The log entries show information about the database tables and columns, which is not directly related to the connectivity issue. However, they do indicate that the application is interacting with the database meaning your database connection is good.

To further investigate and resolve the problem, I recommend the following steps:

1. Check WebApp Configuration: Review the configuration settings for the webapp mentioned in the error logs. Ensure that the necessary connection parameters, URLs, and ports are correctly configured and that tomcat has full permission read and write to /dspace folder.
2. Network Connectivity: Verify that the server hosting the DSpace application has proper network connectivity. Check for any network issues, firewalls, or security settings that might be blocking the connection.
3. SSL/TLS Configuration: If SSL/TLS is in use, review the SSL/TLS configuration for any errors or mismatches. Ensure that the necessary certificates and trust settings are correctly configured.
4. Application Server Logs: Check the logs of the application server (e.g., Tomcat) for any related errors or warnings. They might provide additional insights into the problem.
5. Recent Changes: If any changes were made to the server or application configuration before the issue occurred, consider whether they might have impacted the connectivity.
6. Engage Support: make sure while engaging here for support you give more details about your server and the version of DSpace you are running.

I hope this information assists you in diagnosing and resolving the issue. Please feel free to provide further details or updates on any steps you've taken so far. Also visit the DSpace documentation site https://wiki.lyrasis.org/display/DSDOC7x/
