I uploaded images to a local database from a locally hosted app. It worked fine!
I tried uploading it to an Appharbor MySQL database and I’m getting the following error.
( connection settings are fine. I have tested insertion with sample string and numbers )

What should I do?
You should increase the CommandTimeout or use a something other than a webform to insert the data (MySQL Workbench comes to mind).
