Common Troubleshooting Tips

  • File Encoding: Save your file in standard ASCII / UTF-8 format without special non-English characters.
  • File Extension: Ensure your uploaded file ends with .log or .txt. Binary or Word documents (.pdf, .docx) are rejected.
  • Missing END-OF-LOG: The last line of your log file must explicitly be END-OF-LOG:.
  • Time Format: UTC times should be 4 digits formatted as HHMM (e.g., 1345).
