Fix Mega Connection and Quota Errors — Resolve with RcloneView
Troubleshoot Mega sync failures in RcloneView — resolve overquota errors, authentication problems, and connection timeouts when syncing or transferring Mega files.
Mega is a cloud storage service known for its end-to-end encryption and generous free storage tier. While it works well for manual file access, syncing large amounts of data through Mega using RcloneView can surface specific error conditions: overquota throttling, authentication failures after session expiry, and connection interruptions. This guide covers the most common Mega errors encountered in RcloneView and the steps to resolve them.

Manage & Sync All Clouds in One Place
RcloneView is a cross-platform GUI for rclone. Compare folders, transfer or sync files, and automate multi-cloud workflows with a clean, visual interface.
- One-click jobs: Copy · Sync · Compare
- Schedulers & history for reliable automation
- Works with Google Drive, OneDrive, Dropbox, S3, WebDAV, SFTP and more
Free core features. Plus automations available.
Mega Overquota (Bandwidth Limit Exceeded) Errors
Mega imposes download bandwidth limits — particularly on free accounts — and exceeding them triggers throttling that manifests as "overquota" errors or drastically degraded transfer speeds. When this happens during a sync job in RcloneView, you may see errors containing EOVERQUOTA or similar codes in the Log tab.
Immediate fixes:
- Wait for the quota window to reset. Mega's bandwidth limits reset on a rolling time window, typically several hours. Pausing syncs and retrying later often resolves the issue without any other changes.
- Reduce concurrent transfers. In the sync job's Advanced Settings, lower the Number of File Transfers to 1 or 2. Fewer concurrent connections reduces the rate of bandwidth consumption, helping you stay under the quota threshold.
- Use the Filtering step to limit each sync run to a subset of files, avoiding large single-run transfers that quickly exhaust bandwidth.
Authentication and Login Errors
Mega uses email and password authentication in rclone. Authentication errors typically appear as login failures or session expired messages. Common causes:
Wrong credentials: Verify your Mega email and password in the Remote Manager. If you recently changed your Mega password, edit the remote in RcloneView and update the credentials. Navigate to Remote tab > Remote Manager, select your Mega remote, and click Edit.
Two-factor authentication (2FA): If 2FA is enabled on your Mega account, rclone may have difficulty with standard email/password login. Check Mega's documentation for whether API access with 2FA enabled requires any special token or app password configuration.
Session expiry: Long-running sync operations can outlast a session token. If a job fails partway through with an auth error, re-editing the remote to trigger re-authentication and then resuming the sync resolves this.
Connection Timeouts and Interrupted Transfers
Mega connections can time out during large transfers due to network instability or Mega server-side rate limiting. RcloneView's sync engine retries failed operations automatically (default: 3 retries), so transient failures often recover without intervention. If a job consistently fails after all retries, check the Log tab for specific error messages.
For persistent timeout issues, add the --timeout and --contimeout flags via Settings > Embedded Rclone > Global Rclone Flags to extend the connection timeout values. This gives Mega's API more time to respond before rclone declares a failure.
Resuming Interrupted Mega Sync Jobs
If a large Mega sync is interrupted — whether by overquota, timeout, or a system sleep — re-running the same sync job in RcloneView picks up where it left off. Rclone's incremental sync behavior compares source and destination and only transfers files that are missing or different, skipping everything already transferred successfully.
Getting Started
- Download RcloneView from rcloneview.com.
- Enable DEBUG logging (Settings > Embedded Rclone > Log Level: DEBUG) to capture detailed error output from Mega operations.
- Reduce concurrent transfers in your sync job's Advanced Settings if overquota errors occur.
- Re-edit the Mega remote in Remote Manager to refresh credentials if authentication errors persist.
Understanding Mega's bandwidth and session limitations helps you configure sync jobs that complete reliably without hitting these common error conditions.
