hi. thank you for visiting my topic so i currently develop 2 things: - client side app hosted in vercel - mediasoup app hosted in EC2 (i serve the app using caddy and [nip.io](http://nip.io) for ssl) // this is my webrtc options export const webRtcTransport\_options = () =\> { const HOST\_PUBLIC\_IP = process.env.APP\_ANNOUNCED\_IP; return { listenIps: [ { ip: “0.0.0.0”, announcedIp: HOST\_PUBLIC\_IP, // my public elastic ip in AWS }, ], enableUdp: true, enableTcp: true, preferUdp: true, }; }; first i successfully run an for my learning app from amir essaq tutorial and it worked with above setting this is the port range i used: APP\_RTC\_MIN\_PORT=2000 APP\_RTC\_MAX\_PORT=2020 this is my security group: ![image](https://global.discourse-cdn.com/free1/uploads/mediasoup/original/2X/9/98702c371b68ddf8c5b1e30259277c7c2ae2f38d.png) i notice that the big differences within my app and amir essaq was - amir serve the app on the same domain - i serve my client app on vercel with my mediasoup app in EC2 my app dont recieve any “dtlsstatechange” event is there anything i did wrong and any explanation is welcome 🙂 note: i tested my app locally, and it worked. ---

Check that the ports are reachable from the outside with some simpler tool (netcat, etc). ---

this is the result when i check it, connection to port 7000 seems fine, but i cant reach 2000-2020 ![image](https://global.discourse-cdn.com/free1/uploads/mediasoup/original/2X/b/b24802c679ff33cc22eb92faa9cadb83d9710e30.png) ---

and for more info, my websocket signaling is fine so i can assure that its not a websocket problem (im using socket io) ---

> [@fakhripraya](#): > > but i cant reach 2000-2020 Well, that’s the problem then. Without the connection, there will be no `dtlsstatechange` or any other events. ---

it turns out that its only an env problem i set env value in my worker creation like this, idk why its a problem when i host in ec2, it seems the env value not assigning rtcMinPort: process.env.APP\_RTC\_MIN\_PORT, rtcMaxPort: process.env.APP\_RTC\_MAX\_PORT, now it works with me assigning it with a direct value thanks for visiting and replying to my topic 🙂
