@Nadun,

It seems like the issue is with Roundcube’s SMTP configuration.

Make sure that the SMTP hostname, port, and encryption (SSL/TLS) settings in Roundcube are correct.

@Mario,

Make sure to verify the file and directory permissions, ensuring that the web server has the necessary access to the files. Incorrect permissions could result in a 404 error.

Also, check your configuration settings to ensure they are correctly set up like database connections, and any other relevant configuration details.

In reply to Farhad. @Farhad, The error message you're encountering, "Network is unreachable", typically indicates that your system is unable to establish a network connection to the target IP addresses. This can be due to several reasons such as internet connection issues, network configuration issues, or firewalls or security software blocking a request... The "Connection refused" and "Failed to connect socket" errors indicate that the Roundcube application is unable to establish a connection to the SMTP server. I suggest you check your SMTP server configuration, firewall, or selinux restricting connection, or check that the PHP socket extension is enabled in the PHP configuration. Also, make sure to check SMTP server logs for more information.
