Renter Troubleshooting

Common issues and solutions when renting GPU servers on Clore.ai.

Server Connection Issues

Cannot Connect via SSH

Symptoms: Connection refused, timeout, or permission denied.

Solutions:

1. Wait for server to boot

   • New orders take 2-5 minutes to fully initialize

   • Check order status in "My Orders" - should show "Running"

2. Verify connection details

   • Double-check IP address and port from order details

   • Use the exact command format: ssh root@IP -p PORT

3. Check your network

   • Try from a different network (some ISPs block certain ports)

   • Use Clore VPN if available in your region

4. SSH key issues

   • Ensure your public key is added in Account → SSH Keys

   • Try password authentication if keys don't work

Server Not Responding

Symptoms: Server was working but now unresponsive.

Solutions:

1. Check server status in My Orders

2. Wait 5-10 minutes - server may be restarting

3. Contact host via chat if issue persists

4. Request refund if server is completely unavailable

GPU Issues

GPU Not Detected

Symptoms: nvidia-smi returns error or shows no GPUs.

Solutions:

# Check if NVIDIA driver is loaded
lsmod | grep nvidia

# Restart NVIDIA services
sudo systemctl restart nvidia-persistenced

# Check for driver issues
dmesg | grep -i nvidia

If GPU still not detected:

1. Contact the host via order chat

2. Request server restart through support

3. Consider ending order and finding different server

CUDA Errors

Symptoms: CUDA out of memory, version mismatch errors.

Solutions:

1. Check CUDA version compatibility

   nvcc --version
   nvidia-smi

2. Free GPU memory

   # Find processes using GPU
   nvidia-smi
   
   # Kill specific process
   kill -9 <PID>

3. Use appropriate Docker image with matching CUDA version

GPU Performance Lower Than Expected

Solutions:

1. Check if other processes are using GPU: nvidia-smi

2. Verify GPU model matches listing

3. Monitor GPU utilization during your workload

4. Contact host if specs don't match advertised

Docker / Container Issues

Container Won't Start

Solutions:

1. Check Docker status

   docker ps -a
   docker logs <container_id>

2. Restart Docker service

   sudo systemctl restart docker

3. Check disk space

   df -h

Missing Dependencies

Solutions:

1. Install required packages:

   apt-get update && apt-get install -y <package>

2. Use pip for Python packages:

   pip install <package>

3. Consider using a different Docker image with pre-installed tools

Network Issues on Server

Cannot Access Internet from Server

Solutions:

1. Check DNS

   cat /etc/resolv.conf
   # Try adding Google DNS
   echo "nameserver 8.8.8.8" >> /etc/resolv.conf

2. Test connectivity

   ping 8.8.8.8
   curl -I https://google.com

Ports Not Accessible

Some servers have firewall restrictions:

1. Check which ports are open in order details

2. Use SSH port forwarding for services

3. Contact host if you need specific ports opened

Billing Issues

Charged More Than Expected

1. Check order history for actual usage duration

2. Review fee structure (On-Demand vs Spot rates)

3. Account for creation fees

4. Contact support with order ID if discrepancy exists

Order Terminated Unexpectedly

For Spot orders:

• Another user may have outbid you

• This is normal for Spot rentals

• Use On-Demand for guaranteed access

For On-Demand orders:

• Check if balance was sufficient

• Review order logs for termination reason

• Contact support if unclear

Getting Help

Contact Host

• Use the chat feature in your order details

• Hosts typically respond within a few hours

Clore.ai Support

• Discord: discord.gg/clore-ai

• Use #support channel for technical issues

Request Refund

If server doesn't meet advertised specs:

1. Document the issue (screenshots, logs)

2. Contact host first

3. If unresolved, contact Clore.ai support with evidence
