⚡ Quick Answer
Porofessor usually stops working in-game because of a conflicting app (like Overwolf, CryptoCSP, or ViPNet), an unsupported server/mode (Garena, PBE, Practice/Co-op vs AI), or a display-detection glitch. Porofessor’s own support pages confirm these as the main causes. Closing conflicting overlays, checking your Porofessor settings, and confirming your game mode is supported fixes it in most cases.
📋 TL;DR — Key Points
- Porofessor does not support Garena servers or the PBE (Public Beta Environment) — it never will, per the developer.
- It also doesn’t work in Practice Tool or Co-op vs AI game modes.
- The most common in-game blocker is a conflicting app like Overwolf running alongside Porofessor.
- Champion-select issues are often caused by CryptoCSP or ViPNet security software installed on your PC.
- A “sad poro” error screen usually means a temporary Riot or Porofessor server issue — wait a few hours before assuming it’s broken.
- Always confirm you’re running the latest version of both Porofessor and your League client.

1. Why Porofessor Stops Working In-Game
Porofessor is a live-stats overlay for League of Legends built on the Overwolf platform, and its behavior depends on your game mode, server region, and what other overlay software is running alongside it. According to Porofessor’s own support documentation, most “not working” reports fall into one of two buckets: your setup isn’t supported at all (certain servers or modes), or something on your PC is interfering with the overlay.
What Porofessor does not support
- Garena servers: officially unsupported and not planned to be supported.
- PBE (Public Beta Environment): not supported.
- Practice Tool and Co-op vs AI modes: the in-game overlay does not activate in these modes.
2. Common Scenarios & Their Causes
| Symptom | Likely Cause | Fixable? |
|---|---|---|
| Not appearing in champion select | CryptoCSP/ViPNet software, display detection glitch, or Overwolf conflict | Yes |
| “Sad poro” error picture in-game | Temporary Riot or Porofessor server issue, or unsupported mode/server | Usually resolves itself |
| App won’t log you in | League client not fully launched, or Riot account sync issue | Yes |
| Blurry / glitchy overlay display | Graphics driver or display-scaling conflict | Yes |
| Never works, any mode | Playing on Garena or PBE (unsupported) | Not supported |
3. Fix: Not Appearing in Champion Select
Per Porofessor’s official troubleshooting steps, work through these in order:
- 1. Confirm you’re not on Garena — this server is not supported at all.
- 2. Uninstall CryptoCSP or ViPNet software (CryptoCSP, ViPNet CSP, ViPNet Local Signature Service) if installed — these are known to interfere with the overlay.
- 3. Check your Porofessor settings to make sure champion select display isn’t disabled, and confirm Porofessor is actually running while you’re in champ select.
- 4. Fix a false dual-monitor detection — if you only have one screen, press Windows + P and select “PC Screen Only,” since Windows sometimes misdetects a second display.
- 5. Reinstall via Overwolf — fully close Overwolf from the system tray, uninstall it, then reinstall Porofessor from the official download page.
4. Fix: “Sad Poro” Error In-Game
If you see an in-game error screen with a sad poro image, Porofessor’s support page lists these as the possible reasons:
- Riot server issue: wait and try again; contact Porofessor support only if it persists beyond 24 hours.
- Porofessor servers are temporarily down: wait a few hours and retry.
- You’re on Garena: unsupported, and will not be added.
- You’re in Practice Tool or Co-op vs AI: these modes aren’t supported by the in-game overlay.
- You’re on PBE: unsupported, and will not be added.
5. General Fixes That Apply to Most Cases
Try these regardless of the exact symptom
- Update both apps. Make sure Porofessor and League of Legends are both on their latest versions — the developer frequently ships bug fixes.
- Re-sync your Riot account. If Porofessor won’t log you in, confirm the League client is fully launched and your Riot account is properly connected.
- Check your internet connection. A stable connection is needed for Porofessor to reach both Riot’s servers and its own.
- Restart Porofessor and your PC. This clears most temporary glitches, including display and blurry-overlay issues.
- Reinstall as a last resort. If nothing else works, uninstall Porofessor and Overwolf completely, then do a fresh install from the official site.
6. Frequently Asked Questions
Why isn’t Porofessor showing up in-game?
The most common reasons are an unsupported server (Garena) or mode (Practice Tool, Co-op vs AI, PBE), a conflicting app like Overwolf, or a temporary Riot/Porofessor server issue.
Does Porofessor work on Garena servers?
No. Porofessor’s developer has confirmed Garena servers are not supported and are unlikely to ever be supported.
Why doesn’t Porofessor appear in champion select?
This is usually caused by CryptoCSP or ViPNet software conflicts, a champ-select display setting disabled in Porofessor, a false dual-monitor detection, or an Overwolf conflict that needs a clean reinstall.
What does the “sad poro” error mean?
It typically indicates a temporary Riot or Porofessor server issue, or that you’re playing in an unsupported server/mode such as Garena, PBE, Practice Tool, or Co-op vs AI.
