Need help with error message in log V3.80

Hi guys,

Has anyone else seen this message?

Error while running the 'Keep alive' schedule task. The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

The cert is valid, and it has just recently started. Any ideas as to what this is and why it might be occurring?

Thanks,
Jon

Thanks very much! That helped point me in the right direction and I discovered that the store name was missing the s in the URL of the store name.

Very much appreciated!!!!
