UI & Queue Issues
Queue appears blank / items don’t appear
Symptom: The receiver queue is empty even though the sender has items queued.
Cause: This is usually a stale page or SSE connection issue.
Resolution:
- Refresh the receiver browser tab (
F5orCmd+R) - Check the connection status badge — if it shows Reconnecting or Disconnected, wait for it to turn green
- If the badge stays disconnected, verify the sender is still running
- If items were queued before the receiver connected, they should appear after the initial queue load on connect
“Invalid Date” or garbled text in queue
Symptom: Dates or text in the queue display as “Invalid Date” or appear garbled.
Cause: A browser caching or rendering issue, or a mismatch between an old receiver session and a new sender.
Resolution:
- Hard refresh the page:
Ctrl+Shift+R(Windows/Linux) orCmd+Shift+R(macOS) - If the issue persists, clear browser cache for
localhost - Ensure the receiver URL and secret match the current sender session
404 on sender root / UI does not load
Symptom: Opening http://localhost:5000 shows a 404 or “connection refused”.
Cause: The sender is not running, or is running on a different port.
Resolution:
- Check if the sender process is still running in your terminal
- If it exited unexpectedly, restart it:
cloud-share-sender - If you started with a custom port, use that port:
http://localhost:<port>
File or text size exceeded
Symptom: Upload fails with:
Error: File exceeds maximum size of 100 MB
or
Error: Text exceeds maximum size of 10 MB
Cause: The content is larger than the allowed limit.
| Type | Limit |
|---|---|
| Text | 10 MB |
| File | 100 MB |
| Zip bundle | 100 MB |
Resolution:
- For text: split into smaller chunks, or save as a file and use file transfer
- For files: compress the file first, split it with
split(Linux/macOS) or7-Zip(Windows), or use a different transfer mechanism for very large files - For zips: remove some files from the bundle and send in multiple transfers
Zip password forgotten
Symptom: The receiver downloaded a zip bundle but cannot open it — the password is not known.
Cause: The zip password was set by the sender but not communicated to the receiver, or was forgotten.
Resolution:
The zip password cannot be recovered — it is not stored anywhere in the cloud-share system. The sender must:
- Re-create the zip bundle with a new (known) password
- Queue the new bundle
- Communicate the new password to the receiver through a secure channel
Getting more diagnostic information
For any issue not covered here, run with verbose logging to see detailed output:
# Sender
cloud-share-sender --log verbose
# Receiver
cloud-share-receiver --log verbose
Verbose logging shows:
- DevTunnels CLI output and tunnel creation steps
- All incoming HTTP requests and responses
- SSE connection events and reconnection attempts
- Encryption and hash computation steps (without revealing plaintext)
