Connection Errors

Solutions for network and API-related errors.

Common connection errors

"Unable to connect to server"

The plugin cannot reach our API server.

Solutions:

1. Check your internet connection

   • Open a browser and visit fastrender.ai
   • If the website doesn't load, check your internet

2. Check firewall settings

   • Ensure api.fastrender.ai is not blocked
   • Add an exception if using corporate firewall

3. Try again later

   • Our servers may be temporarily unavailable
   • Check Discord for status updates

"API key invalid"

Your license key is not being accepted.

Solutions:

1. Verify your API key

   • Log in to fastrender.ai/account/api-key
   • Copy the key again (make sure to get the full key)
   • Paste it in the plugin settings

2. Check for extra spaces

   • Ensure no spaces before or after the key
   • Try deleting and re-entering

3. Reset your key

   • If the key was compromised, generate a new one
   • See API Key Management

"Request timeout"

The generation request took too long.

Solutions:

1. Wait and retry

   • High server load can cause timeouts
   • Wait 5-10 minutes before retrying

2. Simplify your request

   • Try a shorter prompt
   • Remove reference image temporarily
   • Use a preset prompt

3. Check your connection speed

   • Slow upload speeds can cause timeouts
   • Test at speedtest.net

"Rate limit exceeded"

You've made too many requests in a short time.

Solutions:

1. Wait before retrying

   • Rate limits reset after a few minutes
   • Avoid rapid repeated requests

2. Check your usage

   • View your usage at fastrender.ai/usage
   • Ensure you have credits remaining

Network troubleshooting

Step 1: Test basic connectivity

Open your browser and visit:

• https://fastrender.ai — Main website
• https://api.fastrender.ai — API endpoint

If these don't load, the issue is your network connection.

Step 2: Check firewall/proxy

Corporate networks often block certain domains. Contact your IT department to allow:

• fastrender.ai
• api.fastrender.ai
• *.amazonaws.com (for image delivery)

Step 3: Test with different network

Try connecting to a different network:

• Mobile hotspot
• Home network (if currently on work network)
• VPN (or disable VPN if currently using one)

Step 4: Check DNS

Flush your DNS cache:

Windows (Command Prompt as Admin):

ipconfig /flushdns

Then restart your browser and Rhino.

VPN considerations

VPN causing issues

Some VPNs interfere with API connections:

1. Try disconnecting VPN temporarily
2. Whitelist FastRender domains in your VPN settings
3. Try a different VPN server location

VPN required for access

If you need VPN for internet access:

• Ensure VPN is stable before generating
• Choose a server geographically closer to the US
• Contact your IT if issues persist

SSL/Certificate errors

"SSL certificate error" or "Certificate invalid"

Solutions:

1. Check your system time

   • Incorrect date/time causes certificate errors
   • Sync your clock with internet time

2. Update Rhino

   • Older versions may have outdated certificates
   • Help → Check for Updates

3. Check for security software interference

   • Some antivirus programs intercept SSL
   • Try temporarily disabling SSL scanning
