Direct answer
Installing the wrong ARM64 or x64 build can cause launch connection symptoms, crashes or poor compatibility. Match the package to your CPU architecture: x64 for most Intel/AMD PCs, ARM64 for Apple Silicon or ARM Windows devices when supported.
What to check first
Each platform has its own permission model. Windows focuses on ports and security prompts, macOS on chip architecture and system permissions, Android on VPN/background behavior, and iOS on App Store proxy clients.
- Match the package to the device platform and CPU architecture.
- Grant only the permissions required by the selected feature.
- Compare the tutorial screenshots with the client version you installed.
- Use platform logs or permission panels when the GUI looks normal but traffic has a problem.
Recommended handling
Keep the troubleshooting path narrow: confirm the profile, confirm the selected node, test Rule mode, read the log, then change only the setting that matches the observed status message.
Practical notes
- Change one setting at a time so the result is attributable.
- Use logs and timestamps when asking for provider or community support.
