| Symptom | Likely Root Cause | Solution |
|---------|------------------|----------|
| Verified missing, but file exists | Checksum mismatch due to ASCII/BINARY mode mismatch | Force binary mode with TYPE I before upload |
| Server rejects 10161oo244 | Token expired or invalid | Regenerate session ID from master control panel |
| Verified appears, but downstream downstream fails | Verification is only for transfer, not virus scanning | Configure server to run clamav post-verification |
| "icc ftp server" unreachable | Firewall or deprecated cipher suites | Test with openssl s_client -connect host:990 -tls1_2 |
| Issue | Why It Breaks Verification | Solution |
|-------|----------------------------|----------|
| Expired certificate | FTPS verification fails | Renew cert, check with openssl s_client -connect ... |
| Mismatched host key | SFTP warns or rejects | Update known_hosts or pin new key |
| Firewall blocking passive ports | Data connection fails | Ensure passive port range (e.g., 30000-31000) open |
| Logging incorrect session ID | Cannot trace event | Use UUIDs or job IDs (10161oo244) in scripts |
| Using plain FTP for ICC | Credentials sent in clear → not verified secure | Migrate to FTPS or SFTP |
