Not a content-marketing exercise. Every entry here exists because somebody asked it, usually more than once, and the answer was worth writing down properly.
Use the browser KVM console in the control panel — it attaches to the virtual machine's display and keyboard directly, so it works regardless of firewall rules, sshd configuration or network state. From there log in at the console with the root password, fix the problem, and reload sshd. If you have also lost the root password, boot into single-user mode by editing the GRUB entry from the same console and appending "init=/bin/bash" to the kernel line.
Check the access instructions sent to the email address on your order after deployment. Keep your order link and SSH private key secure. If you cannot find the credentials or need a reset, contact support from the order email with the order ID; do not send your SSH private key.
The KVM console is in the control panel under your server, and opens in the browser with no plugin or client required. It gives you the virtual machine's display and keyboard from before the bootloader onwards, which means you can interrupt GRUB, boot rescue media, watch the kernel boot, and fix a broken network configuration. It works when SSH does not, which is precisely when you need it.
The key must be an OpenSSH-format public key, on one line, beginning with ssh-ed25519, ssh-rsa or ecdsa-sha2-nistp256. The two most common mistakes are pasting the private key instead of the public one — the public key is the file ending in .pub — and pasting a PuTTY-format key, which uses a multi-line format with a header. Convert a PuTTY key with PuTTYgen's "Export OpenSSH key" option, or run: ssh-keygen -i -f puttykey.pub.
Quote expiry does not reverse a blockchain transfer. If you sent funds before or after expiry, contact support with the order ID, asset, network and transaction hash before paying again. Use the expiry shown for your quote: volatile-asset and stablecoin quotes can have different lifetimes. Payments are verified automatically; server preparation follows confirmation, and network timing varies.
Send the exact crypto amount on the network displayed by checkout, allowing for any fee deducted by your wallet or exchange. Do not assume a short payment will be accepted automatically. If you sent less, contact support with the order ID and transaction hash before sending an additional transfer.
Contact support with the order ID, transaction hash and amount sent so the surplus can be reviewed for a credit or refund. A surplus is not an automatic renewal instruction. Any crypto refund is subject to the published refund terms and outbound network fees.
Cryptocurrency payments are push transactions: NimbusVPS cannot pull a new payment from your wallet. Arrange renewal before the term ends and keep your order email accessible. The published service terms describe suspension and a seven-day post-expiry grace period; keep independent backups and do not rely on an assumed reminder or automatic balance renewal.
Your order record identifies the service configuration, USD total and prepaid term. Keep the order ID and your blockchain transaction reference. If you require a particular accounting or tax document, contact support before purchasing to confirm the document and operator details available; do not assume an automatically generated PDF or VAT invoice.
Steal time records time a virtual CPU was ready to run while the hypervisor scheduled other work. Collect a sample with vmstat 1 30 during the slowdown, note the time and workload, and send it to support with your order ID. One reading does not establish a host oversubscription ratio or prove the cause of an application slowdown.
Use fio with a test file on the intended filesystem and direct I/O when that reflects your workload. Limit the test size and duration, check available space and avoid benchmarking a busy production database. Compare latency and throughput under the same workload; published NVMe or HDD capacity alone is not an IOPS guarantee.
A single TCP stream is limited by the bandwidth-delay product and by any congested hop between you and the server, not by the port speed. Test with multiple parallel streams — "aria2c -x8 -s8" — before concluding there is a problem. If multi-stream throughput is also low, run "mtr --report --report-cycles 50" to the server and open a ticket with the output; loss at the final hop is a real problem and we will look at it.
The published transfer policy throttles the port to 10 Mbps for the remainder of the billing month instead of billing bandwidth overage. If you need more transfer, review the extra-transfer or unmetered option in the configurator and contact support for an existing service. Location, configuration and prepaid term affect the full total; an add-on unit rate is not a standalone server price.
The catalogue uses KVM virtualisation. A supported Linux guest can run Docker or Podman when its kernel and resources meet the software requirements. Choose enough memory and disk for your images and services. Confirm nested virtualisation or other specialist hypervisor features with support before ordering; standard container support does not establish those capabilities.
Custom ISO is an option to discuss with support for your selected configuration and location. Confirm the image architecture, boot requirements, networking and licence before buying. Do not assume every x86-64 image works on every configuration, or that a licence is included unless the order states it.
Windows Server 2022 and 2025 appear in the configurator with base operating-system surcharges of $8 and $9 per month respectively. These are licence add-ons, not complete VPS prices. Both require at least 4 GB RAM and 60 GB disk. Location, hardware and the prepaid term determine the full checkout total; the shortest term is three months.
Contact support or use a rebuild option actually available for your service to confirm the operating system, procedure and any charges. A reinstall can erase the existing disk: make an independent backup and verify it before proceeding. Do not assume an API rebuild endpoint or a fixed completion time.
Check "ip -6 addr show" for an assigned address and "ip -6 route show" for a default route. Most templates configure the first address automatically; if yours did not, the /64 and gateway are shown in the control panel and can be configured through netplan or systemd-networkd. The most common cause of intermittent IPv6 failure is a firewall blocking all ICMPv6 — that breaks neighbour discovery and path MTU discovery, and produces symptoms that look nothing like a firewall problem.
The acceptable-use policy lists Tor exits for the Netherlands, Iceland, Romania and Moldova, and excludes them at the United States location. Confirm the selected location and workload before operating an exit. The Tor-relay option identifies the intended use; it does not exempt a service from complaints or the acceptable-use policy.
The acceptable-use policy permits a legitimate mail server and prohibits unsolicited bulk mail. Confirm outbound port 25, reverse DNS and any requirements for your selected service before buying. An IP address and a working SMTP port do not guarantee recipient acceptance or a particular reputation.
Proof-of-work mining is not permitted on shared VPS hardware. The published policy permits it on dedicated hardware and permits nodes, validators, staking infrastructure and RPC services subject to the service and resource rules. Check current hardware and storage requirements for the software you intend to run.
The acceptable-use policy provides a remediation opportunity where ongoing harm permits, with a published 48-hour window for ordinary cases. Active attacks can require immediate restriction. Preserve relevant evidence, rotate affected credentials and restore or rebuild from a trusted source after assessing how the compromise occurred.
NimbusVPS reviews requests under applicable law and its published privacy and acceptable-use policies. The service retains email, configuration, payment and order-status records; choosing crypto or omitting an ID upload does not make an order untraceable. No published case counts establish how many requests the service has received.
Contact support from your order email with the order ID to arrange cancellation. Back up anything you need before terminating a server. The published seven-day guarantee applies to an eligible new VPS or storage first term, with network fees and stated exclusions; renewals and dedicated servers are excluded. The shortest purchase term is three months, so review the full prepaid total before ordering.
Ask, and if the answer turns out to be generally useful it ends up on this page. First-reply target 12 minutes, 24/7.
Choose your location, resources and term. Pay in crypto after reviewing the total; payment is verified automatically before your VPS is prepared.
