Either your hosts CA truststore is out of date, or you experience the result of a man in the middle attack.
It is not uncommon that companies perform “tls inspection” which can be considered as a planed man in the middle attack.

Please use the forum search with the keywords “tls inspection” and you will find plenty of topics where this has been discussed.
