Sync failures in GitHub Desktop can arise from network problems, conflicting changes, or credential issues. Try refreshing your network or re-authenticating in GitHub Desktop.

Sync issues between GitHub Desktop and the online repository often occur due to network interruptions, unresolved conflicts, or outdated credentials. Begin by testing your network connection to ensure stability. If issues persist, re-authenticate by logging out of GitHub Desktop, clearing saved credentials, and logging back in. For conflicting changes, open the repository in GitHub Desktop, click on 'Current Branch,' and select 'Fetch origin.' Any detected conflicts will display, allowing you to resolve them in the 'History' or 'Changes' tab. Ensuring these elements are updated typically allows smooth syncing between local and remote repositories.
