If you encounter a control panel error and document editor connection issues while installing ONLYOFFICE Workspace v24.10.830 on a Windows Server 2016/2022, the problem may stem from conflicts with OTP and RabbitMQ dependencies. To resolve this, uninstall otp_win and rabbitmq-server, then reinstall the correct versions: otp_win64_23.3 and rabbitmq-server-3.8.35. This ensures proper communication between ONLYOFFICE components, restoring full functionality to the control panel and resolving document editor connection problems. After reinstalling, restart the necessary services and verify that ONLYOFFICE Workspace operates smoothly without further errors.
