Hello,
I currently have the issue, on newly deployed docker installations, that I cannot search for non-indexed extensions.
In the logs I get the following on startup
xwiki | 2026-07-18 21:22:35,940 [extension.index job group daemon thread - org.xwiki.extension.index.internal.job.ExtensionIndexJob@4082f167([extension, index])] WARN o.x.e.i.i.j.ExtensionIndexJob - Failed to get remote extension from repository [extensions.xwiki.org:xwiki:https://extensions.xwiki.org/xwiki/rest\]: IOException: Invalid answer [500] from the server when requesting [https://extensions.xwiki.org/xwiki/rest/repository/search?start=0&number=100&q=\]
And when searchig I get
xwiki | 2026-07-18 21:46:38,024 [http-nio-8080-exec-3 - http://localhost:8080/bin/admin/XWiki/XWikiPreferences?section=XWiki.Extensions&search=openid+authenticator&repo=&recommended=false&indexed=false&compatible=on&compatible=false\] ERROR o.x.e.r.i.RepositoryUtils - Failed to search on repository [extensions.xwiki.org:xwiki:https://extensions.xwiki.org/xwiki/rest\] with query [org.xwiki.extension.index.IndexedExtensionQuery@e777024]. Ignore and go to next repository.
xwiki | org.xwiki.extension.repository.search.SearchException: Failed to search extensions based on pattern [openid authenticator]
xwiki | Caused by: java.io.IOException: Invalid answer [500] from the server when requesting [https://extensions.xwiki.org/xwiki/rest/repository/search\]
When I try browsing to the page I get a Cloudflare Captcha - maybe that’s the issue why XWiki cannot access it (?)
Thanks
