|
|
```
|
|
|
|
## Configurare ngrok
|
|
|
|
**Configurare**: `/root/.config/ngrok/ngrok.yml`
|
|
|
|
```yaml
|
|
version: "2"
|
|
authtoken: 2mo9quiDc23B6U3TtTqWJEleEfM_jYeD1KYe9u7njaaQMZg2
|
|
tunnels:
|
|
web:
|
|
proto: http
|
|
addr: http://10.0.20.161:3000
|
|
domain: mutual-special-koala.ngrok-free.app
|
|
```
|
|
|
|
**Serviciu systemd**: `/etc/systemd/system/ngrok.service`
|
|
|
|
**URL public**: https://mutual-special-koala.ngrok-free.app
|
|
|
|
**API endpoint chatbot**:
|
|
```
|
|
POST https://mutual-special-koala.ngrok-free.app/api/v1/prediction/d4911620-07fe-41f8-adb4-f2f52d6ec766
|
|
```
|
|
|
|
**Comenzi utile**:
|
|
```bash
|
|
# Status
|
|
pct exec 104 -- systemctl status ngrok
|
|
|
|
# Restart
|
|
pct exec 104 -- systemctl restart ngrok
|
|
|
|
# Verificare tunel activ
|
|
pct exec 104 -- curl -s http://localhost:4040/api/tunnels
|
|
|
|
# Verificare versiune
|
|
pct exec 104 -- /usr/local/bin/ngrok --version
|
|
|
|
# Actualizare ngrok
|
|
pct exec 104 -- /usr/local/bin/ngrok update
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### Eroare CORS
|
|
**Simptom**: Browser-ul afișează eroare CORS când se încarcă chatbot-ul.
|
|
|
|
**Cauza**: Flowise nu are configurată variabila `CORS_ORIGINS`.
|
|
|
|
**Soluție**: Adaugă în `/etc/systemd/system/flowise.service`:
|
|
```
|
|
Environment=CORS_ORIGINS=https://www.romfast.ro,https://romfast.ro
|
|
```
|
|
Apoi: `systemctl daemon-reload && systemctl restart flowise`
|
|
|
|
### Eroare ngrok versiune veche (ERR_NGROK_121)
|
|
**Simptom**: În logs apare:
|
|
```
|
|
Your ngrok-agent version "3.16.0" is too old. The minimum supported agent version is "3.19.0"
|
|
```
|
|
|
|
**Cauza**: ngrok a fost actualizat dar serviciul nu a fost restartat. Procesul vechi continuă să ruleze.
|
|
|
|
**Soluție**:
|
|
```bash
|
|
# Actualizare (dacă nu e deja făcută)
|
|
pct exec 104 -- /usr/local/bin/ngrok update
|
|
|
|
# IMPORTANT: Restart după actualizare
|
|
pct exec 104 -- systemctl restart ngrok
|
|
```
|
|
|
|
### Verificare rapidă că totul funcționează
|
|
```bash
|
|
# Test local Flowise
|
|
pct exec 104 -- curl -s http://localhost:3000/ | head -5
|
|
|
|
# Test tunel ngrok
|
|
curl -s "https://mutual-special-koala.ngrok-free.app/api/v1/prediction/d4911620-07fe-41f8-adb4-f2f52d6ec766" \
|
|
-X POST -H "Content-Type: application/json" \
|
|
-d '{"question":"test"}'
|
|
```
|

## Istoric incidente
|
|
|
|
### 2025-12-30: Chatbot nu funcționa (CORS + ngrok versiune)
|
|
- **Problemă 1**: Flowise nu avea CORS configurat
|
|
- **Problemă 2**: ngrok rula versiunea 3.16.0 (actualizată dar nerestartat din octombrie)
|
|
- **Soluție**: Adăugat CORS_ORIGINS și restart la ambele servicii
