### ⚠️ OTP Issue / URL not accessible :

* Install ngrok in different tab on the same vps ( don't close previous tab where gensyn is running)

```
wget https://bin.equinox.io/c/bNyj1mQVY4c/ngrok-v3-stable-linux-amd64.tgz && tar -xvzf ngrok-v3-stable-linux-amd64.tgz && sudo mv ngrok /usr/local/bin/
```

* Now visit : <https://ngrok.com/>
* Sign up using email
* Now go to `Your authtoken` section and then click on "show authtoken" option and then copy that command
* Now open your VPS in other tab and paste the command
* Now use this command `ngrok http 3000`
* Then click on the following url with ngrok domain and then access gynsyn page and login using email address (✅ working, tested)
