**Short answer:** Check these first: the red 'Instagram conection expired' banner (reconnect), your credits, the Global and DMs switches in Account Settings → Automation, whether the comment contained your trigger word, and whether it was a reply inside a thread. Then read the comment's tag in the post's All Comments tab and the reason in Automation Recovery → Missed & Failed.

## Before you start

- Test from a **second Instagram account**, or ask a friend to comment. That is the only way to see what a follower sees.
- Comment on the post itself, not as a reply under another comment.

## Steps

1. Look at the top of any InstantDM page. If you see "Instagram conection expired! Automation Stopped.", click **Connect Instagram Directly** (or **Connect Instagram via FB Page** on the Facebook banner) and log in again. See [reconnect Instagram](https://instantdm.com/how-to/reconnect-instagram.md).
2. Click **Account Settings** → **Automation**. Check that **Global** and **DMs** are **On**, then click **Save**.
3. Open **Insights** and look at **Plan Credits**. On Free, if you have no credits left, nothing is sent.
4. Open the post: **Quick Automation** → the **Instagram** tab → **Posts** → click the post → **All Comments**. Find the comment and read its tag (see the table below).
5. Open **Automation Recovery** → **Missed & Failed**. Each row shows what happened and Instagram's reason underneath.
6. Fix the cause, then send the missed DMs again with **Resend**. See [resend missed DMs](https://instantdm.com/how-to/resend-missed-dms.md).
7. Still stuck? Click **Need Help?** at the bottom of the left menu, or email hey@instantdm.com.

## Most common causes

Start at the top.

| What you see | What it means | What to do |
|---|---|---|
| Red banner "Instagram conection expired! Automation Stopped." | Instagram signed InstantDM out, often after a password change | Reconnect, then resend. [Reconnect Instagram](https://instantdm.com/how-to/reconnect-instagram.md) |
| Nothing at all for that comment | It was a reply inside a comment thread | Only top-level comments start an automation |
| No DM, and the comment didn't contain your word | The trigger word didn't match | A word in the comment must **start with** your trigger word: "link" matches "links" but not "blink". Capitals and accents don't matter. [Trigger words](https://instantdm.com/how-to/how-trigger-words-work.md) |
| No DM, and the comment had extra words (Lead Gen or flows) | **Match exact word only** is on, so the comment must be only the word | Turn it off, or ask people to comment only the word |
| **No automation configured** | The post had no automation when the comment came in | Set up the automation. Older comments can be answered with [Re-run](https://instantdm.com/how-to/rerun-missed-comments.md) |
| **Out of credits** in Missed & Failed | You had no credits left | Upgrade or renew, then **Resend** |
| Nothing is sent from any automation | **Global** is **Off**, or your plan ended (the account is then on Free with 0 credits) | Turn **Global** on, or renew in **My Plan** |
| Public reply posted, no DM | **DMs** is **Off**, or Instagram refused the DM | Turn **DMs** on. Check Missed & Failed |
| **Rate limit reached** | Your hourly pace was reached (Free and Legend Pro) | Wait, or raise **Automations / Hour**. [DMs per hour](https://instantdm.com/how-to/how-many-dms-per-hour.md) |
| **Scheduled** ("Waiting in Queue") | Queued because of a busy hour (Trendsetter and Multi) | Nothing. It will be sent |
| **Instagram limit reached** | Instagram asked your account to slow down | InstantDM retries after your **Rate Limit Retry** time |
| **Message rejected** in Missed & Failed | Instagram refused the DM | Read Instagram's reason under the row. See the list below |
| They got a button, but not the link | Your **Welcome Message** or flow sends a button first | Expected. The rest comes after they tap the button |
| They got "🔓 Follow to Unlock Exclusive Content" | Your follow gate is on and Instagram says they don't follow you | [Follow message keeps coming](https://instantdm.com/how-to/follow-message-keeps-coming.md) |
| The comment isn't in **All Comments** at all | Instagram never told InstantDM about it | [Re-run missed comments](https://instantdm.com/how-to/rerun-missed-comments.md) or Comment Pooling (Trendsetter and above) |
| **Flow stopped** in Missed & Failed | A flow stopped at a step Instagram refused | Fix the cause, then click **Continue** |

## Less common causes

- **The person is in Whitelist Contacts.** Whitelisted people get no automation at all. Check **Account Settings** → **Automation** → **Whitelist Contacts**.
- **A DM keyword or story reply was skipped while you were chatting.** **Prevent In-Chat Trigger** skips these if your account sent a message in that chat recently, including messages from your automations. See [Automation tab switches](https://instantdm.com/how-to/automation-settings.md).
- **"Any Message" replied only once.** **First time only** replies once per person, ever. **Once a day** replies at most once every 24 hours. This is expected.
- **A story reply didn't trigger.** Only text replies count. Stickers, photos and reactions don't.
- **A story mention didn't trigger.** InstantDM has no story-mention trigger.
- **A post shared to your DMs didn't trigger.** **Automate Post sent to your DM** must be on for that post, it only works for your own posts, and it needs Instagram login. See [post shared to DMs](https://instantdm.com/how-to/reply-when-post-shared-to-dm.md).
- **Send Link and Lead Gen are both on for one post.** Only the one you saved last runs. Use one or the other.
- **You edited a Lead Gen post in the phone app.** Publishing that post's automation in the app removes the Lead Gen set up on the web. Set it up again on the web.
- **A flow was switched off or deleted** while someone was in the middle of it. They stop where they were. Set the flow live again.
- **They tapped a button from another app** (for example Instagram's own chat buttons). Only InstantDM's buttons continue an InstantDM automation.

## When Instagram refused the DM

You may also get an email about these. See [InstantDM's warning emails](https://instantdm.com/how-to/instantdm-emails-explained.md).

- **They don't follow you:** InstantDM posts your **Comment Reply for Non-Followers** under their comment instead. See [non-followers](https://instantdm.com/how-to/dms-to-non-followers.md).
- **Your Instagram DMs are turned off:** turn message access back on in Instagram. The email "Your Instagram DMs are turned off" links a short video.
- **Missing permissions:** reconnect and approve every permission on Meta's screen.
- **Another app controls the chat** (for example ManyChat or Meta Business Suite): the email "Some Instagram replies aren't going out — quick fix" links a video with the setting to change.
- **Your account is limited:** see [Instagram limited my account](https://instantdm.com/how-to/instagram-restricted-my-account.md).
- **Too old:** "Instagram no longer allows a reply to this — it is too old". Comments can get a DM within 7 days, messages within 24 hours.

## On the phone app

- A "Connection Expired" banner on the Instagram screen means you must reconnect. Tap it.
- Home → **Instagram** → **Posts** → tap the post → **Contacts** tab. Each person shows **DM Sent** with a tick or a cross, and the error reason under **Show More**.
- Switches: profile photo → **Settings** → **Automation** (**Global Automation**, **DM Replies**).
- Failed DMs: Home → **Automation Recovery** → **Missed & Failed**.

## What you can't do

- DM people who never commented or messaged you.
- Send a DM after Instagram's window has closed.
- Trigger an automation from a reply inside a comment thread or from a story mention.

## Questions people also ask

**I commented my own keyword and nothing happened. Is it broken?**

Not necessarily. To see what a follower sees, test from a second Instagram account, or ask a friend to comment on the post.

**The public reply was posted but no DM arrived. Why?**

Check that DMs is On in Account Settings → Automation. Then look in Automation Recovery → Missed & Failed: Instagram may have refused the DM, for example because the person doesn't follow you.

**It worked yesterday and stopped today. What changed?**

Most often the Instagram connection expired (look for the red banner), credits ran out, or a plan ended. A paid plan that ends moves the account to Free with 0 credits.

**Can I send the DM to the people who were missed?**

Yes, within Instagram's limits. Resend refused DMs from Automation Recovery, or use Re-run missed comments on the post (Trendsetter and above).
