Failed by ICE timeout - Server behind NAT

[Intergon]

Hello,
I moved our testing server behind NAT and installed newest version, I redirected ports on router, and opened ports on firewall.
And now I am getting "Failed by ICE timeout"

I am sending a few logs, could you help with it?

Best regards, Damian.

Hello
Make sure UDP ports reachable
https://docs.flashphoner.com/display/WCS52EN/Accessory+tools#Accessorytools-Portroutingchecking
As an option you can try to switch to TCP and check ports using telnet
https://docs.flashphoner.com/display/WCS52EN/Publishing+and+playing+stream+via+WebRTC+over+TCP
default media port range: 31000-32000

UDP ports are reachable.
Iptables output:

Above ports are also forwarded on router.

Please chek your ip and ip_local settings in flashphoner.properties.
ip should be set to external IP address, and ip_local should be set to WCS server LAN IP address, for example

ip=172.24.223.11
ip_local=192.168.1.5

 

[Intergon]

Yes, that was the problem. I have dynamic DNS, and in IP field I set dyndns host, not external IP.. When I set external IP it works. Could you support dynamic hosts in this configuration field?

 

[Max]

We think about it, but not in near future

 

[Intergon]

Ok, thanks for solving

 

[Max]

Good day.
We have checked if latest builds from this page work with dynamic DNS hostname in ip field. It works, you can set ip=hostname.dyndns.com. But there can be issues when external IP address or something else is changing in DNS records, in this case either WSS connection cannot be established or publishing can fail or so on until record changes are deployed over all the DNS servers.

 

[Intergon]

Yeah, so it will be better to make shell script to periodically check public IP, and when it changes, update ip in config file and automatically restart server..

 

[Max]

It's no so good for production, so we recommend to use static white IP for production server.

 

[Intergon]

Of course

in 2 way streaming - if one of the parties is behind NAT it can happen as well. any idea how to fix it ?
