| Cannot sign in | Account | Reset password or verify SSO credentials |
| Settings do not persist | Account | Clear browser cache β retry in alternate browser |
1. Chat Issues
1.1 No Response
Symptom: Message sent; no output appears.
Resolution:
- Wait 60 seconds. Complex prompts and larger models require additional processing time.
- Click [Regenerate] to retry the request.
- Send a minimal test prompt (
"Hello?") to isolate whether the issue is prompt-specific or systemic. - Refresh the page and retry.
If all steps fail: The service may be temporarily unavailable. Wait 10 minutes and retry. If the issue persists, escalate via Support & Escalation.
1.2 Incorrect Output
Symptom: IAN returns factually incorrect, fabricated, or off-topic content.
Resolution:
- Request source attribution: Prompt
"Quote the exact text or source where you found that."Verify the cited passage against the original material. - Increase prompt specificity: Vague prompts produce lower-accuracy outputs. See Best Practices Β§1.1.
- Regenerate: Click [Regenerate] β the same model may produce a more accurate response on a subsequent attempt.
Compliance note: Do not rely on IAN as the sole source of truth for claims, compliance, legal, or financial decisions. Always verify against official sources or consult a subject-matter expert.
1.3 Missing Chat History
Symptom: A previous conversation is no longer visible.
Resolution:
- Open History in the sidebar. Use the search box to locate by keyword.
- Open Saved in the sidebar. Starred chats are retained indefinitely.
Prevention: Star (β) any conversation you will need to reference later. Starred chats do not expire.
1.4 Rate Limit Exceeded
Symptom: Error message indicating too many requests.
Resolution: Wait 5 minutes, then continue normally.
If recurring: Request a rate limit adjustment from your organization admin.
1.5 Truncated Response
Symptom: Output stops mid-sentence.
Root cause: The response exceeded the model's per-response output token limit.
Resolution: Type "Continue" or "Keep going". IAN resumes from the point of truncation.
1.6 Context Window Exceeded
Symptom: IAN no longer references information from earlier in the conversation, or produces contradictory statements.
Root cause: The conversation length has exceeded the model's context window capacity.
Resolution:
- Start a new chat.
- In the first message, provide a summary of prior findings:
"Here's what we established so far: [summary]. Now let's continue withβ¦"
Prevention: Keep conversations focused on a single topic. Start a new session when the topic changes substantially.
2. Document Issues
2.1 File Upload Failure
Symptom: File does not attach or upload errors on submission.
Diagnostic checklist:
| Check | Requirement | Resolution |
|---|---|---|
| File size | β€20 MB per file; β€50 MB total per message | Split file into smaller parts |
| File format | PDF, DOCX, TXT, CSV, or XLSX | Convert to a supported format |
| File integrity | File opens normally on local machine | Re-download or re-save the file |
If all checks pass:
- Try drag-and-drop instead of the [Attach files] button (or vice versa).
- Retry in a different browser.
- Re-save the file (File β Save As β new copy) and retry.
2.2 Unreadable File
Symptom: IAN returns a "can't read file" error.
| File type | Root cause | Resolution |
|---|---|---|
.doc (pre-2007 Word) |
Unsupported legacy format | Open in Word β Save As .docx |
| Password-protected PDF | IAN cannot decrypt protected files | Remove password protection, re-save |
| Scanned document (image-only PDF) | No extractable text layer | Process with OCR software before uploading |
Proprietary formats (.pages, .numbers) |
Not supported | Export to PDF or DOCX |
Quick diagnostic: Open the file and press Ctrl+A (Select All). If text is highlighted, IAN can process it. If nothing highlights, the file is image-based and requires OCR preprocessing.
2.3 Incorrect Document Output
Symptom: IAN makes claims about the document that do not match the actual contents.
Resolution:
- Request a verbatim quote:
"Quote the exact paragraph where you found that." - Verify the quote against the source document.
- If the quote is accurate but the interpretation is wrong: Provide additional context:
"When this document says [term], it means [your definition]." - If the quote is inaccurate or fabricated: The model misread the document. Rephrase the question or switch models.
2.4 PDF Table Extraction Errors
Symptom: Table data from a PDF is malformed, merged, or incorrectly structured.
Root cause: PDF table layouts are visually rendered, not structurally encoded. Text extraction frequently fails to preserve column/row relationships.
Workaround:
- Copy the table data from the PDF.
- Paste into the chat message or a plain text file.
- Describe the structure explicitly:
"Here's a table with columns: Date, Amount, Region." - Submit the query against the pasted data.
Preferred alternative: If the source data is available in CSV or XLSX format, upload the spreadsheet instead. Structured file formats produce significantly more reliable extraction.
2.5 Context Loss on Long Documents
Symptom: IAN produces incomplete or inconsistent answers when processing documents exceeding ~50 pages.
Root cause: Document length approaches or exceeds the model's context window capacity.
Resolution:
- Split the document into 3β5 sections by topic or chapter.
- Upload one section per chat session.
- Summarize each section independently.
- Open a final chat, paste all summaries, and prompt:
"Synthesize these findings into one overview."
For the full segmented analysis workflow, see Best Practices Β§3.4.
3. Account Issues
3.1 Sign-In Failure
| Symptom | Resolution |
|---|---|
| SSO authentication failure | Verify you are using your p-number (not email address). Confirm MFA device is available. |
| Account locked | Wait 15 minutes for auto-unlock. If still locked, contact support. |
| "Access denied" error | Account may not yet be provisioned. Allow a few hours for propagation. If unresolved, contact support. |
For full sign-in procedures, see Sign In & Account Setup.
3.2 Settings Not Persisting
Symptom: Changes to user settings revert after navigation or page refresh.
Resolution:
- Refresh the page and retry.
- Retry in a different browser.
- Clear the browser cache:
Ctrl+Shift+Deleteβ clear cached files β refresh.
If unresolved, contact support.
Escalation Procedure
If no resolution above addresses the issue:
- Document the scenario: what action was taken, what occurred, and what was expected.
- Capture a screenshot of any error message.
- Submit via Support & Escalation.
