@jnfrmarks I assume there is a test plan for server-to-server sharing - can you please have a close look at the log files and watch out for errors like the one above?

Generally speaking any error with app: PHP shall be reported. Many thanks!

@MorrisJobke thx for return

@diablotin84 So you used the URL from the public share page and not the download lunk provided by the input field below the file preview. Can you test this with the download URL (direct link)? Thanks

[diablotin84]

I have click on Share and Share link, it's not right ?

[MorrisJobke]

@diablotin84 On master this simply downloads a HTML page - the page that is shown if you browse that link. Then there is a direct link on that page. If you enter that one, the correct file is downloaded to your ownCloud. THis for for me here on master. No errors at all (for both links)

[diablotin84]

@MorrisJobke OK thks for return, i have now a new error in my error log apache2

Invalid method in request quit

any idea ?

Sincerely

Does the remote server have a valid SSL certificate ?

Hi, i have the same issue when adding a URL from a remote ownCloud server, trying to create a server-to-server share:

"Error fetching URL"

The client fires an AJAX request:
https://[SERVER]/index.php/apps/files/ajax/newfile.php?dir=%2F&source=...&filename=public.php%3F...&requesttoken=...

The result is:
"Invalid name, '', '/', '<', '>', ':', '"', '|', '?' and '*' are not allowed."

apps/files/ajax/newfile.php, line 68:
if(!OCP\Util::isValidFileName($filename)) {
$result['data'] = array('message' => (string)$l10n->t("Invalid name, '', '/', '<', '>', ':', '"', '|', '?' and '*' are not allowed."));
OCP\JSON::error($result);
exit();

It seems like the GET variable "filename" is checked for containing illegal characters. But it's set to the URL of the shared resource, so isValidFileName checks against "index.php?...", and fails for the "?".

Hope that helps to fix the problem.

Please don't use "Add from URL" to add remote shares. You should open the link directly and then click "Add to ownCloud" instead.

Also the feature "Add from URL" has been removed as per #14652 (many security issues)
