Can't get online no matter what I do.

Post by lotus10 »

Hi guys.
All is set correctly but I can't get online.
1. Http and Stream are enabled,
2. UPNP is enabled and running.
3. Despite UPNP I manually forwarded the ports: 8888 -TCP and 8081 - TCP/UDP
4. Firewall settings configured to allow Java through.
What else is there to do?

Are you using the the function:
"Help -> Am I online?"
when you try?

Some routers won't let you connect to your own public address and see your self.
(That's why the "Am I online?" function was created)

Yes, I'm using the function "Am I online?", I am doing it on a remoter computer I'm connected to with TeamViewer11.
When I paste the remote computer's public address into the browser on my machine the page won't load.

I'm unsure but I believe there may be a bug in the IP address detected and provided by Yawcam. The IP address provided by Yawcam on my stream is incorrect and not the actual IP. You might try a test by detecting your actual IP via:

https://www.iplocation.net/

Then try to access using this IP along with the appropriate port number.

[Edit] Nevermind, there's no bug. Yawcam is working properly as to the detection of the external IP. Since I use a DDNS resolver and never bother with IP addresses, I do not have the 'Detect at startup' option checked In the 'Connection' setting. Thus, the displayed IP and reported URL would not match my actual IP. FYI.[/Edit]

I tried 2 more programs - Webcam Surveyor and Webcam 7. I can connect over the LAN but no success connecting over the Internet. Apparently something is blocking the connection but I can't figure out what it is.

Good. I just had to make sure you were testing the correct way.
Another thing I want to double check is that you have made the firewall configurations for javaw.exe. Please note the w at the end of the file name. This is the java file that starts Yawcam and will need a rule in the firewall.

But since you are having the same connection problem also with other software it's probably not the case with a misspelled rule in the firewall...

Let's also double check that the port is listening for connections.
Start Yawcam and enable the stream output.
Open a command prompt (click on Windows start menu, type "cmd", hit enter)
Run this command in the command prompt:

Code: Select all

netstat -anop tcp | find ":8081"
That is if you are using the default port number 8081. Otherwise you have to change 8081 in the command to the port number you are using.

Is should look something like this:
Listening on port 8081
Listening on port 8081
yawcam_listening.PNG (5.25 KiB) Viewed 39193 times
Do you get any result when you run the command?

Is 51.210.188.58 your actual IP? You're trying to access Yawcam on a Government network? I don't think they would let you have access--major security risk, external network access is typically blocked. FYI.

MA_Angel - for privacy reasons I photoshopped one digit in that public IP. I am not in a UK Government Department, lol.

If only we're mindreaders, troubleshooting would be so much simpler... ;)

Does your PC have any anti-virus program(s) running its own firewall?

Did you verify that your actual WAN IP address matches the external IP displayed by Yawcam?

By "actual WAN IP" you mean my public IP, like that displayed at https://www.iplocation.net/ ? It does match the IP detected by Yawcam.
I don't use any antivirus/ firewall software, only Windows firewall. I temporarily disabled it but nothing changed.
The laptop I am trying to stream from is connected to the internet via wireless network, maybe the problem has anything to do with that...

Yes, WAN IP = Public IP, just want to double check. :)

I'm unfamiliar with the D-Link DSL-225 router, but a quick scan of its user manual seems to indicate that there may be two possible built-in firewalls that could interfere with access. You might thoroughly check the router's configuration settings to be sure that they're indeed proper for your DSL and LAN networks.

Might also try different unused/unassigned port numbers between 49152 to 65535.
More info: https://en.wikipedia.org/wiki/List_of_T ... rt_numbers
Your ISP could be blocking some of the ports...

As to the PC being wirelessly connected--or hardwired--to the LAN, be sure that the PC is assigned and configured in the router to use a static LAN IP so that port forwarding would work properly and solely with that PC.

Appreciate your willingness to help!
I tried all of your suggestions but to no avail.
The computer has a static IP - 192.168.1.100, all outgoing IP traffic from LAN is allowed in the router settings, ports are forwarded and "listening".
Even tried disabling the router's firewall - didn't help.

I'm stumped, and I've just one final suggestion... Since you've manually forwarded the ports, try disabling UPnP in both the router configuration and Yawcam settings--just in case if there's any conflict and/or incompatibility.

Strange! Feels like you tried all options by now...
I just want to double check: Did you try changing the port numbers?

It might be a good idea to ask your ISP if they are blocking any ports.
And while you are at it, also verify that your ISP gives you a public IP address and don't run your traffic via a proxy of some kind.
