Hi,

I found that on my site no thumbnails (from www.airport-data.com ) showing up anymore.
After hours of debugging my network without effect, I found that installations with mono throw such an error:

http://sdr1hgn.ddns.net:8090/VirtualRad ... umThumbs=2
http://shineadsb.ddns.net:8085/VirtualR ... umThumbs=2
http://trackadsb.com/VirtualRadar/Airpo ... umThumbs=2

All show:

{"status":500,"error":"Exception caught while fetching thumbnails: Error: TrustFailure (Authentication failed, see inner exception.)","data":[]}

Installations with other than mono-servers work:
http://can.vicosh.ro:8000/VirtualRadar/ ... umThumbs=2
http://flightradar.hochstaffl.eu/Virtua ... umThumbs=2

{"status":200,"data":[{"image":"https://cdn.airport-data.com/images/air ... ":"Raymond Zammit"},{"image":"https://cdn.airport-data.com/images/air ... r":"Thomas Ramgraber"}]}

How can this br resolved?

Thanks

I have noticed this issue on my server as well.

Is there any workaround?

NB On at least one of the links posted by OP (http://trackadsb.com/VirtualRadar/desktop.html) images are displayed for some aircraft, but for those aircraft, I don't see the call to AirportDataThumbnails.json being made?

Did you ever get a workaround for this? I have the same issue and unable to fix it.

There are other sources of images with open APIs I believe, if the existing provider doesn't like VRS users from using their images.

Unfortunately no, I found never a solution for this...

My programming skills are way to limited. To me, it looks like a bug in airport-datas-API. It worked a long time and without doing anything on VRS, it stopped working. So Id say VRS is not the source of the problem. The people on airport-data must have changed something.

I dont know if we can change the picture-provider? I think there is an option to enable this feature in general, but no option to select another provider. I assume airport-data is hard-coded in VRS.

Unless airport-data reverts their API-change or VRS gets updated to use another provider (or let us choose antoher one), I see no way to get the pictures back. But as told above, Im not a programmer. Maybe a simple fix could be implemented, but thats beyond the scope of my knowledge.

Played a bit in Wireshark, this is the TCP-Stream of a connection to airport-data:

GET /api/ac_thumb.json?m=5110F3&r=ES-ACM&n=2 HTTP/1.1
Host: www.airport-data.com

HTTP/1.1 301 Moved Permanently

<h1>Moved Permanently</h1>
<p>The document has moved <a href="https://www.airport-data.com/api/ac_thu ... re</a>.</p>
</body></html>

Id say, VRS wants:

Code: Select all

www.airport-data.com/api/ac_thumb.json?m=5110F3&r=ES-ACM&n=2

but this rescource has moved to:

Code: Select all

www.airport-data.com/api/ac_thumb.json?m=5110F3&amp;r=ES-ACM&amp;n=2

This means the amp; behind the "&" is needed now. Colud this lead to the error...???
