Is it my FTP program or WU that dumps an idle FTP WebCam connection after 60 Seconds. 
If an image is uploaded every hour then the WU status is always offline due to connection lost and I loose my Gold Star.

It is normal for a receiving FTP server to close the idle connection. You can't stay connected. WU stipulates that FTP upload be done in 5 minute increments or longer. Your FTP client needs to initiate a connection each time and then after uploading is complete it needs to disconnect (or you will get kicked off). Typically the image you are FTPing should take less than a second to upload. I don't think Gold Stars are awarded for Webcams.

So uploads need to be 5 min or less in frequency.  Thats odd as I see some webcams just showing 8 slides for the day.  As for My profile showing the WebCam Offline, I guess that is normal as it is only on for a minute before being kicked off.  My WebCam is linked to my PWS and since it has been configured my Gold Star disapeared.  i am going to kill the Web Cam profile and see if it returns as its been gone for a while now.

No, let me clarify. Do not upload FTP image any quicker than 1 image every 5 minutes. I upload 1 image every 10 minutes just because it suits me. That said though just because you upload every 5 or 10 minutes or every hour if that is what you wish there is a good chance that the uploaded image will not make it into the system for viewing because of the current state of WU servers. There are 3 FTP servers that correspond to webcam.wunderground.com. Out of the 3 IP addresses that resolve that DNS name only 1 of the IP addresses works. But even that one that does work is iffy. So you stand less than a 1 in 3 chance of your FTP upload working out each instance. So uploading every hour is probably not going to give good results because you stand a chance of less than 1 image every 3 hours making it. That is why I do every 10 minutes. Why not do the maximum of every 5 minutes? Well the results I'm getting gets me enough frames per day to play the little movie in WU webcam interface. I want it to be quick and I don't need more details.


As for Gold Stars those come and go and they aren't in your control. They just aren't working well. They have nothing to do with Webcams. Gold Stars have to do with your temperature is all as it compares to neighbors. But even that is a stretch. Just forget about the Gold Stars...there is nothing you can do regarding them. If your station has good reporting connectivity to the Internet and your temperature sensors is accurate then there is noting more to do. You will still loose the Gold Star because WU servers are being worked on and it gets constantly reset. Trust me it isn't worth even thinking about them. It has been like this for over a year. There were actually some months were they were gone for everyone.

Many thanks for the informative update George.  
In your PWS profile does your status for the WebCam show Offline ?. 
Wonding if thats normal given FTP is only online for a blink ever 5 to 10 min or so when pic uploaded.
Do you know the IP for the working FTP server.
Cheers Mike

My WU FTP Webcam status shows Online. I upload every 10 minutes to webcam.wunderground.com. I don't upload to the known working IP because the results I'm getting suits me. I'm waiting for the day all 3 FTP servers start working. I may then need to decrease upload to 1 image per 30 minutes. I don't want a long movie for each day. I just want a quick few frames. More isn't always better.


WU camera FTP address:

webcam.wunderground.com


DNS resolves to:

52.36.136.128

54.148.11.142

52.37.52.183


The known working IP lately has been 52.36.136.128 and you can check this message thread for recent discussions regarding the FTP status.

Thanks for that,  It looks like I will have to use a dedicated IP Cam with internal FTP server to send snapshots from normal video stream as my Dahua NVR 7108HS-8P will not allow snapshot filenames to be changed to image.jpg as req by WU and the minimum selectable FileSize to FTP in the NVR is 1MB which is rejected by WU.
Any NVR solution gracefully received.
