Hi @RTL8710, I'm not clear as to what problem you're facing. The only errors I see are:

2023-06-06 08:10:14 WARN handleStunPacket():2447 Unable to fetch request Timestamp from the hash table. No update to totalRoundTripTime (error code: 0x40100001)
2023-06-06 08:10:14 ERROR handleStunPacket():2554 operation returned status code: 0x40100001
2023-06-06 08:10:14 ERROR incomingDataHandler():2312 operation returned status code: 0x40100001

The error code comes from one of the dependencies of our SDK here. These can be safely ignored. Can you please elaborate further on the issue you're facing? Are you able to see the stream on the JS viewer when you use the sample?

Could you provide us some more context on what steps were needed in order to encounter this error?

Was it previously working and now it is not working? Sometimes failing? Always failing?

Are you using master branch? Which device are you running this on? Any code changes you made? What are you using as viewer?

[RTL8710]

candidate use server extend ip as views
and device as master in host 。

[RTL8710]

@niyatim23 @niyatim23 use master branch。
ice code not change， if device in local ，can see the stream。
but device use srflx ，offer ,answer,candidate signal command success ，but ICE iceAgentCheckCandidatePairConnection error，ICE_AGENT_STATE_MACHINE_STATES Always 0x0000000000000002。

Hi @RTL8710, I wonder if your network setup supports STUN. Can you please run the discoverNatBehavior from our samples to understand what is suitable path? Have you disabled TURN? Do you see any stream when you use TURN?
