Alexa Echo Skill Error in log

Hello all,
I've noticed in the logs for the Alexa Echo Skill that it recorded at least 2 batches of 503 Errors. There was a batch around 9pm last night and around 11am this morning. Is this something that happens normally on occasion or is it something I need to look into?

Error string...
AlexaDeviceStateStoreService returned an HTTP 503 Service Unavailable error.

Alexa seems to continue to work alright I just don't like seeing 'Error' in the logs.

Yep. See this thread:

Thanks, when I searched for 503 I didn't see this thread come up.

I had this same occurrence last night. I started the Echo Skill App and then hit done and then safely rebooted the hub and it went away.
