+[IPFS Check](https://check.ipfs.network/) helps determine the retrievability of a CID from IPFS Mainnet, either from a specific peer given a multiaddress, or from multiple providers.

+Each error type output by the tool can indicate a solution to your problem:
 
 - **Could not connect to the multiaddr** indicates that machines on the internet cannot talk to your machine. Fix your firewall, add port forwarding, or use a relay.
 - **Could not find address in the DHT** indicates that your machine is either not connected to the Amino DHT (even as a client), or it is not advertising the address that you are using to test.
 - **Multihash not advertised in the DHT** indicates that your machine has not advertised that it has the requested content in the Amino DHT. If you're using Kubo, enable the [Accelerated DHT Client](https://github.com/ipfs/go-ipfs/blob/master/docs/experimental-features.md#accelerated-dht-client).
-- **Peer has not responded that it has the CID** indicates that your node cannot find the data that you believe it has, or that there may be some other sort of network latency.
+- **Peer has not responded that it has the CID** indicates that your node cannot find the block that you believe it has, or that there may be some other sort of network latency.
