Hi John,
Based on my experience, this error usually is caused by incorrect system time.
And as we know first place to check is ExchangeSetup.log, open the log file and press Ctrl+End, you will reach the end of the file the place where our error will be available. Then check the
validity of certificate(Start time and End time), if the certificate is valid, please make sure your system time is correct.
And if the certificate is expired, you need to renew the certificate.
