Slow discovery of peers on localhost

[pasqui23]

I have an application that emits peer events very slowly. As in,if I open 2 tabs in the same browser,the second tabs discover the first after a few minutes,but the fist discover the second after a few hours.

Could you try testing version 2.0.1 to see if it's better?

[tinchoz49]

Hey @RangerMauve, sorry, are you sure was published? https://www.npmjs.com/package/hyperswarm-web I cannot see it in versions

[RangerMauve]

@tinchoz49 Whoops, I must have forgotten to publish after tagging. Try 2.0.2 instead. 😅

[pasqui23]

Updated to 2.0.2,still having the same problem

[RangerMauve]

Weird. Lets debug this a bit further.

1. Are you getting anything interesting in the dev tools? Like errors or warning messages.
2. Are connections actually being made to the signalling servers?
3. What browser version are you using?
4. What data are you trying to replicate?

[pasqui23]

1. No,no message at all
2. I have bootstrap:["ws://localhost:4799"],how do I check it?
3. Chromium 83.0.4103.116 4: WHat you need toknow exactly?

[tinchoz49]

Hey @pasqui23, it could be helpful a demo repository with your failing test, we can try to find the issue from that point.

https://github.com/pasqui23/.hswm-bug gets 404

[pasqui23]

It's a private repo,now you should be able to open it.

[tinchoz49]

thank you

there is a typo in the bootstrap url, it should be: ws://localhost:4977

[pasqui23]

I'm using it without TLS,wouldn't break oon wss?

[tinchoz49]

I didn't write wss..

You wrote localost, should be localhost

[pasqui23]

The risks of programming at midnight ...

[pasqui23]

Fixed typo,but discovery is still slow

[pasqui23]

Still important to me and I don't know how to start debugging hyperswarm.Any tips,@tinchoz49 @RangerMauve ?

[tinchoz49]

I don't see the slow discovery

[RangerMauve]

I don't have time at the moment to look too deeply into this due to work, but you could try setting up breakpoints inside the simple peer code to see if you're actually getting peers through it.

[pasqui23]

It looks like the _onIceCandidate ( https://github.com/feross/simple-peer/blob/0dd27ee83d615a8ff0eb48c49ed4917c9d6e2ff1/index.js#L904 ) method fires several times without discovering any peer,is that normal?

[tinchoz49]

which browser are you using?

[pasqui23]

@tinchoz49 still the same.I'm debuuging using VSCode's Debugger for chrome extension

[tinchoz49]

I cannot reproduce your error, in chrome I get a connection in less of 1 second: https://github.com/RangerMauve/hyperswarm-web/issues/7#issuecomment-692747458

[pasqui23]

@RangerMauve where do you suggest I put breakpoints? My selection of breakpoints interrupts right after continuing from the previous breakpoint.

[pasqui23]

I suspect it's something with [https://en.wikipedia.org/wiki/Internet_in_Italy](Italian Internet) as other people in Italy could replicate the problem.

[pasqui23]

@RangerMauve I did set up a breakpoint on Peer._onIceCandidate and it did fire up but still no discovery The about:webrtc of this session so that someone more familiar with webrtc can look it up.

[RangerMauve]

You could try setting up custom TURN servers for your app with a service like XirSys to improve browser-to-browser connectivity. Else you might want to find a consultant that can figure out why WebRTC isn't working for you. 😅
