I have the same problem. I did re-install the plugin and found the api version. (Unraid API v4.27.2+375dcd05) Is there anything else I need to do or information to troubleshoot this problem? Fixed. Updated from 7.2.0 to 7.2.2
I too am getting the following msg: mosquitto_pub: error while loading shared libraries: libssl.so.3: cannot open shared object file: No such file or directory
My broker is set up on another system and I have all the host, port, username, pw and client_Id setup.
Hope someone can help with a FreeFileSync batch operation run by cron on an unraid server. I can see it start and via the FFS page it completes the compare but never does a Sync operation.
