Network Behavior & Troubleshooting
Networking Behavior by Server State
| State | Network Access | Public IP Status | SSH / RDP / HTTP / API Access | Notes |
|---|---|---|---|---|
| Running | Full network communication | Available | Accessible (depends on whether services are started) | Server is up; all services running normally |
| Terminated | Network resources destroyed | Released | Completely inaccessible | Server deleted; all resources unrecoverable |
| Queued / Provisioning | Network not yet initialized | Not ready | Not accessible | Server is being created or initialized |
Common Networking Issues
| Issue | Common Causes |
|---|---|
| Cannot SSH (Linux) | Wrong Public IP, SSH service not started, or the OS firewall is blocking port 22. |
| Cannot RDP (Windows) | Wrong Public IP, RDP service not started, or the OS firewall is blocking port 3389. |
| API / Web Service Not Accessible | Service is bound only to 127.0.0.1 (localhost), incorrect port configuration, OS firewall blocking access, or the service is not running. |
| Port Blocked | The following TCP ports are blocked by default at the platform level: 135-139, 427, 445, 593, 1024-1030, 1080, 1363-1377, 3128, 8888, 9999, 5985, 389, 4444, 3333, 14444, 33333, 2222, 22222. Most AI workloads (FastAPI, vLLM, TGI, ComfyUI, etc.) are not affected. If your application uses a blocked port, switch to an open port such as 8000, 8080, or 5000. |
PTR (Reverse DNS)
PTR records are supported for most IPs. The following IP ranges do not currently support PTR:
77.xxx.xxx.xxx, 93.xxx.xxx.xxx, 83.xxx.xxx.xxx, 155.xxx.xxx.xxx, 38.xxx.xxx.xxx
To set up a PTR record, provide the target domain, and our technical team will assist with configuration.
Bandwidth
All servers provide unmetered network bandwidth. 100 Mbps / 500 Mbps refers to the port speed, not a monthly traffic cap. There is no per-GB billing.
