4 Common Mistakes & One-Click Fixes

The issues below are ranked by frequency of occurrence. Each includes symptom descriptions, root causes, and specific solution steps.

1

API Token Expired — Platform Connection Lost

Most Common
Typical Symptoms
When publishing, a specific platform keeps showing "Posting" or "Failed" while others work fine. In the account management page, that platform's account shows a red warning indicator next to it.
Root Cause: API authorization tokens for platforms like Instagram and TikTok typically have an expiration period (ranging from 60 days to 1 year). Once expired, FlowNIB can no longer perform publishing actions on your behalf and needs to be re-authorized.
Fix Steps:
  1. Go to the "Account Management" page in the FlowNIB dashboard
  2. Find the platform account showing "Disconnected" or a red indicator
  3. Click the "Reconnect" button, which will redirect you to the platform's authorization page
  4. Confirm authorization, then return to FlowNIB — the account status will turn green
  5. Re-publish the previously failed post

⏱ Estimated time: 2 minutes | Recommended: Check account connection status once a month

2

AI Rewrite Output Doesn't Match Expectations

Second Most Common
Typical Symptoms
The AI-rewritten content has the wrong tone, misses key information, or includes phrasing unrelated to your brand. When previewing, you notice the output has strayed from the original intent.
Root Cause: The quality of AI rewriting heavily depends on the clarity and completeness of the input. If the original content contains special characters (like emoji, unusual symbols), messy formatting (excessive line breaks/indentation), or heavy mixed-language text, the AI's parsing accuracy decreases. Additionally, missing platform-specific style presets can lead to unstable output.
Fix Steps:
  1. Check that the source content is clean — remove excess formatting, special characters, and messy line breaks
  2. Make sure you've configured style presets for each platform (tone, formality level, word count range)
  3. Click the "Regenerate" button in FlowNIB — the AI will produce a new version based on the same input
  4. If still not satisfactory, manually edit the key parts and save as "My Rewrite Template"
  5. Next time you have similar content, reuse the template for much more consistent output

⏱ Estimated time: 3-5 minutes | Recommended: Set up 3-5 commonly used rewrite templates in advance

3

Content Format Incompatible with Target Platform

Common
Typical Symptoms
Some platforms succeed while others fail during publishing. The failing platforms usually return specific error messages, such as "Image format not supported" or "Content exceeds character limit."
Root Cause: Different platforms have different content format requirements. Instagram doesn't support GIF as a static post image, LinkedIn has size requirements for article link previews, TikTok videos have specific duration and resolution limits — when FlowNIB detects incompatibility during publishing, it interrupts the posting for that platform.
Fix Steps:
  1. Check the error logs in FlowNIB to find the specific failure reason
  2. Adjust the content format based on the prompt (replace image format, shorten copy, adjust video dimensions)
  3. In the publish preview, review the version for that specific platform to confirm everything is compliant
  4. Re-attempt publishing, or remove that platform from the batch and handle it separately

⏱ Estimated time: 5-10 minutes | Recommended: Use FlowNIB's preview feature to check each platform before publishing

4

Content Throttled or Removed by Platform After Publishing

Requires Attention
Typical Symptoms
FlowNIB shows "Published," but the content does not appear on the target platform, or it appears and is later removed, or engagement data looks unusual (impressions without interactions).
Root Cause: The platform's content moderation system. Certain keywords, link formats, or image content may trigger the platform's automated review rules, causing the content to be flagged as spam or violating guidelines. This is not a FlowNIB issue but a limitation of platform policies.
Fix Steps:
  1. Log into the respective platform's backend to check for violation notices or content removal records
  2. Adjust the content based on the platform's guidance (remove sensitive terms, modify link format, replace images)
  3. Re-publish through FlowNIB after modifications, or test by posting manually from the platform directly
  4. Build a brand vocabulary list marking known sensitive terms to prevent future content from triggering issues

⏱ Estimated time: 10-15 minutes | Recommended: Pre-screen content with platform policy check tools before publishing

FAQ

Frequently Asked Questions

What is the most common reason for FlowNIB posting failure?
An expired API Token is the most common reason. Instagram and TikTok API authorizations typically need to be reconnected every 60 days. We recommend checking your account connection status once a month.
What should I do if AI-rewritten content quality is inconsistent?
Check two things: first, whether the source content is clear — vague input produces vague output; second, check if special characters or formatting are interfering with AI parsing. Clean up the original formatting and try again.
Why did content post successfully on one platform but fail on others?
This is usually a format compatibility issue with the target platform. Check the error message from the failed platform and adjust your content format accordingly. FlowNIB's publish preview feature can catch these issues before you post.
How can I quickly troubleshoot FlowNIB distribution problems?
Follow this sequence: check account connection status → review API error logs → check content format compatibility → verify platform publishing rules → contact support. 80% of issues can be identified in the first two steps.
