Any one can rectify this issue... 404 /server not available

[Jayachristrayar S]

 I recently attempted to install DSpace-CRIS 7, following the documented steps meticulously. Unfortunately, I encountered an issue when trying to access the server. When I navigate to http://82.112.238.193:8080/server, the page displays a "server not found" error.  Checked all log files to diagnose any errors.

• All logs indicate no errors, suggesting that the services may be running without issues.
• However, accessing the server via http://82.112.238.193:8080/server returns a "server not found" error.

 HTTP Status 404 – Not Found

Type Status Report

Message The requested resource [/server/] is not available

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
