I have been performing syncs from several (8+) RACHEL devices housing KA-Lite to the Hub at Learning Equality. For the most part, these have been successful. However, occasionally I receive sync errors that say:
KA Lite host is currently unreachable (connection_error): https://kalite.learningequality.org
Can someone help me diagnose what would cause this to happen, aside from a loss of connectivity. I can confirm that I can access the url in a browser while connected to the RACHEL device and I can confirm that syncs have worked with these devices before.
