After applying recent SAS^® Viya^® 3.5 updates, the Transport Layer Security (TLS) certificate for SAS Configuration Server (Consul) might no longer contain localhost in the Subject Alternative Names, leading to error messages similar to the following:

This issue occurs due to a recent change in sas-bootstrap-config. The changed behavior might not retrieve localhost and other local host names from the /etc/hosts file, depending on the order of names in the file.

To work around this problem, complete the steps in (Optional) Configure Network Settings of the SAS Viya 3.5 Administration to configure the SAS_SAN_DNS variable, ensuring that the variable contains localhost and all other desired Subject Alternative Names.
