Widget Connector problem on Confluence 6.4.2 and Confluence 6.13.4

Question

Hello everyone,

I have some problems with youtube video links provided by widget connector on Confluence 6.4.2, error appear:

Timeout while getting placeholder. Please try again shortly.

I placed this youtube link to my twitter and publish it with widget connecter without any problem and video is loading normally. Proxy and ReverseProxy is configured correctly.

But beside that issue we are upgrading confluence to 6.13.4 and I can't find it on other macros. Did something change on it? I see its available for this version:

Thanks for help!

Getting this same issue on Jira 6.13.4. Existing Widget Connector Macros are working as expected, but new ones are getting the "Timeout while getting placeholder" error. All the WebDAV and Widget plugins are enabled under Plugins > System.

Hello Daniel,

I've upgraded Test instance to 6.13.4 but after paste youtube url its not changing to widget connector. When I try manually add it with widget connector same error occur, from atlassian-confluence.log error:

I've google it and find solution:

https://jira.atlassian.com/browse/CONFSERVER-53469

add value in setenv.sh to:

CATALINA_OPTS="-Dconfluence.macro.placeholder.timeoutMillis=10000 ${CATALINA_OPTS}"

error changed to:

Hi Mateusz, welcome to the Community!

First of all, I need to advise you about a known CVE with your version of Confluence and the widget connector. This can lead to some unpleasant hacking attempts against your Confluence server which I describe in this linked article. The good news is that 6.13.4 that you noted you're looking to upgrade to is patched for these vulnerabilities. Short term, it's possible that your administrator disabled the Widget connector already (but if not, I'd strongly urge an upgrade than trying to fix the issue you're seeing now).

In recent releases of Confluence, there's no explicitly macro that you call. You basically paste the URL of the content you want to add, and Confluence automatically converts it to a macro.

Here's an example video:

Cheers,
