BUG: Tunnels Sometimes Fail to Turn On

Introduction Turning on a tunnel is a crucial feature in many applications, especially those that require secure and private internet connections. However, some users have reported that their tunnels sometimes fail to turn on, either not working at all or taking multiple seconds to activate. This article aims to provide a detailed analysis of this issue, including the steps to reproduce it, expected behavior, and additional context.

Describe the Bug Turning on a tunnel sometimes (or rather, most of the times) either doesn't work or it takes multiple seconds. With 3.6.6, it was reliable and instantaneous. This indicates that the issue is specific to the latest version of the application, 3.7.0, and may be related to changes introduced in this update.

Smartphone Information The issue was reported on a Pixel 8 smartphone, which is a popular device among Android users. The device is running on Android Version 15, which is the latest version of the operating system. The application version is 3.7.0, and the backend is set to Userspace.

To Reproduce To reproduce the behavior, follow these steps:

Try to enable a tunnel.

Expected Behavior The expected behavior is that the tunnel should turn on instantly and reliably, without any issues or delays. However, in this case, the tunnel sometimes fails to turn on or takes multiple seconds to activate.

Screenshots (Not Necessary) Since the issue is related to the application's functionality, screenshots are not necessary to reproduce the behavior.

Additional Context To further investigate the issue, the user tried cleaning app data and reinstalling the application from a different source (Play Store -> GitHub Release). However, these attempts did not resolve the issue. The user also provided logs from where they tried enabling tunnels multiple times, sometimes it worked sometimes it didn't. The logs can be found at logcat_1741700019493.txt.

Reverting to Previous Version Reverting to version 3.6.6 fixes these issues, indicating that the problem is specific to the latest version of the application.

Comparison with Similar Issues The user had a look at #609, where the device and Android version are the same, but the errors are different. Additionally, the user's tunnel is IPv4, which may be a contributing factor to the issue.

Conclusion In conclusion, the issue of tunnels sometimes failing to turn on is a significant problem that affects the reliability and performance of the application. The steps to reproduce the behavior are straightforward, and the expected behavior is that the tunnel should turn on instantly and reliably. The additional context and comparison with similar issues provide valuable insights into the problem. Reverting to the previous version of the application fixes the issue, indicating that the problem is specific to the latest version.

Possible Causes Based on the information provided, possible causes of the issue include:

Changes introduced in the latest version of the application
Issues with the Userspace backend
IPv4 tunnel configuration
Device-specific problems

Recommendations To resolve the issue, the following recommendations can be made:

Investigate the changes introduced in the latest version of the application and identify the root cause of the problem
Test the application with different backend configurations to determine if the issue is specific to the Userspace backend
Verify the IPv4 tunnel configuration and ensure that it is correct
Test the application on different devices to determine if the issue is device-specific

Future Development To prevent similar issues in the future, the following development recommendations can be made:

Implement thorough testing and quality assurance processes to identify and fix issues before they reach production
Regularly review and update the application's documentation to ensure that it is accurate and up-to-date
Provide clear and concise instructions for users to troubleshoot and resolve issues
Continuously monitor user feedback and reports to identify and address potential issues early on.
