OpenSearch addon validation failed

Hello.
I am trying to upload a simple search addon for my website to AMO, but addon automatic validation returnes an error “Your add-on failed validation with 1 error. Received an empty response from the server; status: 0”. After a few attempts to upload an addon, I have also tried other different OpenSearchDescription, but all of them failed with the same messages.
This is an example of the search descriptions, which causes https://addons.mozilla.org/en-US/developers/addon/validate show error message:

<?xml version="1.0" encoding="UTF-8"?>
<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">
  <ShortName>Search YouTube</ShortName>
  <Description>Search YouTube</Description>
  <Tags>youtube video</Tags>
  <Image height="16" width="16" type="image/vnd.microsoft.icon">https://www.youtube.com/favicon.ico</Image>
  <Url type="text/html" template="https://www.youtube.com/results?search_query={searchTerms}&amp;page={startPage?}&amp;utm_source=opensearch" />
  <Query role="example" searchTerms="cat" />
</OpenSearchDescription>

This is probably bug 1193594. Can your confirm?

This bug has RESOLVED status, but my problem is still here. Looks like it is something else.

That patch for this bug has not been pushed to our production servers yet. Would you mind trying on our stage server http://addons.allizom.org?

Addon validation there is working fine. Thank you! I will wait for the patch to be pushed.

Thanks for testing. I hope we can push this fix along with some other this week.
