Hello @mccoysc

The DHT is not enabled by default on js-ipfs at the moment. You can check how to use it through js-ipfs#optionsexperimental. Let us know if this did not solve your problem.

We are working on having it enabled by default in a near future, you can track this on js-ipfs#856

in browser ,i config the dht to be true，the error appear again

[alanshaw]

@mccoysc can you post the code you're using to configure the DHT and the code you're calling to cause this error?

[alanshaw]

ping @mccoysc

[mccoysc]

really,"time out" should not be an error.
when time out,the function should rerurn an error object or undefined but cause an error thrown

[mccoysc]

and also, it's not work well.
await ipfs.dht.findpeer("QmXp22HFGvo29o6dsGnJwxaHvTieEqMGr1pS55ZsZUonMf")
"QmXp22HFGvo29o6dsGnJwxaHvTieEqMGr1pS55ZsZUonMf" is node itself,should not be time-out,but timed-out

[mccoysc]

and if await ipfs.dht.findpeer("QmZ6YuHZUJd6k9hbJNaNUZBsWfwZGv62piZMU6oxHPBtDx"),it works well.
so, the dht can't find the node itself?

[daviddias]

@mccoysc can you share a full example of how you are creating the node and making this call?

[mccoysc]

just like the code in this issue

[alanshaw]

This is because the DHT module is not passed to libp2p in the browser. In 0.34 DHT will be enabled in the browser also.
