After updating coolwsd and code-brand to the 23.05.8.4 deb Package I can’t connect from Nextcloud anymore. I get this error message on the Webbrowser trying to open the Document: “Failed to establish socket connection or socket connection closed unexpectedly. The reverse Proxy might be misconfigured, …” The syslog shows this messages: ![image](https://europe1.discourse-cdn.com/flex013/uploads/collaboraonline/original/2X/d/d6a17f45e55150575f36794cdd19c60960f9a20c.png) I didn’t make any changes to the apache2 proxy config and none to coolwsd.xml requests to /hostin/discovery and /hosting/capabilities work for the coolwsd URL and the Proxy Host URL Any Hints? Please let me know if you need more / other Data Thanks Fred --- _[View the full topic](https://forum.collaboraonline.com/t/failure-after-code-update-to-23-05-8-4-deb-package/2368)._
