Description (partial)

Connection failures can occur when SSL decryption is being performed on connections to sites with large certificate sizes of 16K or greater.

This can happen for any TLS connection when SSL decryption is enabled regardless of whether the connection matches a decryption or do not decrypt rule.

This issue is present when an SSL inspection policy is in place on the affected versions of Firepower Threat Defense devices.
