TL;DR

Pass verbose: true in the second argument to fetch() to gather more information about the socket connection closure.

Guidance

• The error messages suggest a connection issue, possibly related to certificate verification or socket closure.
• To mitigate this, try passing verbose: true as suggested in the error message to gather more detailed information.
• Investigate the certificate verification error by checking the validity of the certificate used by https://downloads.claude.ai/claude-code-releases/latest.
• Consider checking network connectivity and firewall settings to ensure they are not interfering with the connection.

Example

No code snippet is provided as the issue does not explicitly mention a specific code block that needs modification.

Notes

The provided information suggests a potential issue with the certificate verification process or network connectivity, but without more context or details about the environment and the code being executed, it's challenging to provide a definitive solution.

Recommendation

Apply workaround: Pass verbose: true to fetch() to gather more information, as this might help in identifying the root cause of the connection issue.
