Please perform the following steps to enable debug level tracing:
1. Go to the program folder of the cloud connector (Usually at C:\Program Files (x86)\Layer2 Cloud Connector) where you´ll find a configuration file named Layer2.Data.Synchronization.Service.exe.config.
2. Open that file with a text-editor and locate the entry:
<setting name="GlobalLogLevel" serializeAs="String">
<value>Debug</value>
</setting>
This setting defines the minimum level of logging information written to the log files. Set it to the lowest level possible, which is the trace-level, by modifying the <value>Debug</value>-entry to <value>Trace</value>.
This also decreases the synchronization-performance significantly so be sure to set it back to <value>Debug</value> for productive use of the cloud connector. (You can even set it to <value>Info </value> later to further increase performance)
3. Open the log-folder of the cloud-connector and delete the System.log file, which contains detailed information about the processing of all connections.
4. Now just start a run of your troublemaking connection.
5. There should now be a new System.log containing a load of entries about the synchronization run.
6. Please analyse this file for possible issues or send to sales@layer2.de to take a look.
