I am unable to submit files via Switch Client even though nothing has changed on my Switch Server or Switch Client
This can be caused by an large amount of files on the Switch Server in the local user temp folder.
Delete all or most of the temp files located in the temp folder.
Be sure to stop all Switch Processes first. You can double check that all processes are stopped in Task Manager/Activity Monitor.
Delete temp files from this folder:
Hit Command-Shift G and then type in /tmp. This will take you to the temp folder on Mac.
Restart Switch Services and see if the issue is resolved.
This issue is fixed in Switch 2017. Please upgrade to Switch 2017 or higher to avoid having this issue in the future.
