If your Reddit Ads campaigns are stuck on “Pending approval” for more than 24 hours, you are not alone. Advertisers across r/RedditforBusiness and r/advertising report the same issue: ads sitting in review limbo with no notification, no rejection, and no clear explanation. The root cause can range from simple configuration mistakes to platform-level bugs — and, critically, to VPN or ad blocker interference disrupting the Reddit Ads API. This guide walks through every known cause and actionable fix.
Common Causes of Reddit Ads Stuck in Pending Approval
| Cause | How It Manifests | Likelihood |
|---|---|---|
| Expired campaign end date | Ad never enters review queue properly | High |
| Manual review delay (weekends, sensitive content) | Approval takes 48–72 h instead of the standard 24 h | High |
| VPN / ad blocker blocking ads-api.reddit.com | ERR_CONNECTION_CLOSED or 503 errors in browser console | High |
| Platform-side JavaScript bug | Campaign state gets stuck; UI shows pending indefinitely | Medium |
| Overly restrictive audience targeting | Triggers additional manual review steps | Medium |
| Account or session conflict | Resolves after switching to incognito window | Low |
How to Diagnose the Problem Before Fixing It
Check the Browser Console for API Errors
Open your browser’s Developer Tools (F12) and navigate to the Console tab while on the Reddit Ads dashboard. Look for any of the following red flags:
- ERR_CONNECTION_CLOSED — the browser cannot reach Reddit’s ad API endpoint.
- 503 from ads-api.reddit.com — the server is actively refusing or dropping the connection.
- Uncaught SyntaxError on Performance.measure() — a front-end JavaScript bug that can abort the campaign submission script, leaving the campaign in an undefined state.
Any combination of these errors means the problem is not your ad creative or targeting — it is a broken communication channel between your browser and Reddit’s backend.
Identify Whether a VPN or Ad Blocker Is Involved
Proton VPN with NetShield enabled is a known culprit. NetShield filters traffic at the DNS level and can inadvertently block or interrupt domains like ads-api.reddit.com, producing exactly the ERR_CONNECTION_CLOSED and 503 errors described above.
- Other VPN providers with built-in ad/tracker blocking can cause identical symptoms.
- Browser extensions such as uBlock Origin, Ghostery, or Privacy Badger may also intercept API calls to Reddit’s ad infrastructure.
- Corporate firewalls and strict DNS resolvers are additional sources of the same connectivity failure.
Step-by-Step Fixes for Reddit Ads Pending Approval
Fix 1 — Disable VPN Blocking Features First
- If using Proton VPN, go to Settings → NetShield and switch the filter from “Block malware, ads & trackers” to “Block malware only”.
- Reload the Reddit Ads dashboard and check if console errors disappear.
- If errors persist, disconnect the VPN entirely and retest — this confirms whether Proton is the source.
- If you must keep the VPN active, try a different server or protocol (WireGuard vs. OpenVPN) to rule out server-specific blocks.
Fix 2 — Remove Browser Extensions and Use Incognito Mode
- Open a private/incognito window (no extensions loaded by default).
- Log in to Reddit Ads and check your pending campaign.
- If the campaign status updates or the console shows no errors, a browser extension was the culprit — disable them one by one to identify which.
Fix 3 — Correct the Campaign End Date
- Navigate to your ad group settings.
- Verify the end date is set to a future date. An already-expired end date can prevent the ad from entering the review queue at all.
- Update the date, save the ad group, and wait up to one hour for the review queue to pick it up.
Fix 4 — Contact Reddit Ads Support with Evidence
If the issue persists after more than 24 business hours, escalate with data rather than a vague support ticket. Include:
- A screenshot of the browser console showing ERR_CONNECTION_CLOSED or 503 errors from
ads-api.reddit.com. - Your campaign ID and the exact date the ad entered “Pending approval” status.
- Confirmation of the steps you already tried (VPN off, incognito, different browser, different network).
Providing this level of detail signals a platform-side bug and helps the support team escalate internally rather than sending generic troubleshooting replies.
What NOT to Do While Waiting for Approval
⛔ Do not delete and re-upload the ad. This resets your position in the review queue entirely, adding more waiting time rather than speeding things up.
⛔ Do not duplicate the campaign repeatedly. Multiple pending copies of the same creative can flag the account for additional manual scrutiny.
Quick Reference: Pending Approval Troubleshooting Checklist
- ✅ Check browser console for ERR_CONNECTION_CLOSED or 503 errors
- ✅ Disable NetShield / VPN ad-blocking features and retest
- ✅ Disconnect VPN entirely to isolate the variable
- ✅ Open Reddit Ads in incognito mode without extensions
- ✅ Try a different browser (Chrome, Firefox, Edge) on the same network
- ✅ Try a different network (mobile hotspot vs. office Wi-Fi)
- ✅ Verify campaign end date is set to a future date
- ✅ If over 24 business hours with no movement, contact support with console screenshots and campaign ID
- ✅ Do not delete or re-upload the pending ad
Most cases of Reddit Ads stuck in pending approval resolve once the network interference is eliminated or the end date is corrected. When the issue is a genuine platform bug — confirmed by API errors in the console — submitting a detailed support ticket with technical evidence is the fastest path to getting your Reddit Ads campaign back on track.
