I try to submit a webapp to Mozilla's Firefox Marketplace but the validation fails.
The manifest is located here: https://www.bonner-nacht.de/manifest.webapp
The validator complains:
Error while requesting icon
Error: A remote resource was requested, but an error prevented the request from completing. This may include connection, DNS, or HTTP issues.
Requested resource: https://www.bonner-nacht.de/img/logos/BonnerNacht48.png
webapp.manifest
and also
Error while requesting launch_path
But you can perfectly access those resources from any client I tested. Also I am quiet sure that this did work a few days ago.
In Apache's log I can see that Mozilla's server downloads the manifest but does not continue to request the other resources.
Anyone knows what the problem could be?
I reported a bug at https://bugzilla.mozilla.org/show_bug.cgi?id=875142 and I figured out the cause of this problem. The webapp validator uses python-requests library for retrieving http resources which does not SSL support server name indication (SNI), which is needed if you operate multiple virtual hosts with different domain names on a single IP.
