CloudDBError: Chain validation failed

Hi App Inventor,

I am using the storage component CloudDB in my app for the last one week. It had been worked very nice till yesterday.

But today, i am getting an error:
CloudDBError: Chain validation failed

How can i rectify this error?
Please tell me the remedy to overcome this error.
Otherwise my app may stop working.

Awaiting reply

The MIT CloudDB server is currently offline for users using the default. The default server frequently glitches over weekends and periods of high use.

If you want/ require reliability, please use your own Redis server. The default server is for testing.

MIT has been informed. Perhaps service will return soon.
