also wanted to find out if the same option httpchk will work for https?

Change get to GET, at least apache, ngingx and tomcat expect GET not get.
Or test with for example netcat that your server1 accepts get.
Something like: nc server1.add.re.ss 8093
get /nexus/v1/repository/rawcentral/com.att.swm.attpublic/healthcheck.txt
HTTP/1.1
Host: ...
Authorization: Basic ...

Like Jonathan said "No Host" is telling you what's wrong.
(HTTP/1.1 requests expect Host: header).
