TL;DR

Investigate the compatibility of the Linux guest OS with Windows ARM64 (Snapdragon) and consider updating the VM configuration or the Linux kernel to resolve the connection timeout issue.

Guidance

• Verify that the Linux guest OS is compatible with the Windows ARM64 (Snapdragon) architecture and check for any known issues or limitations.
• Check the VM configuration to ensure that it is properly set up to communicate with the host machine, including the network settings and any required ports or protocols.
• Consider updating the Linux kernel or the VM configuration to a version that is known to work with Windows ARM64 (Snapdragon), if available.
• Review the related issues (#40198, #30566, #30864) to see if they provide any insight or solutions to the problem.

Notes

The issue seems to be related to the compatibility of the Linux guest OS with the Windows ARM64 (Snapdragon) architecture, and resolving this may require updates to the VM configuration or the Linux kernel.

Recommendation

Apply a workaround by investigating alternative VM configurations or Linux kernels that are known to work with Windows ARM64 (Snapdragon), as updating to a fixed version is not explicitly mentioned in the issue.
