Web Adaptor install on linux

[TonyCallender]

I tried to use the ./configurewebadaptor.sh, and it returns unable to connect to Portal URL 

./configurewebadaptor.sh -m portal -w https://<web server>.sbcounty.gov/<web adaptor name>/webadaptor -g https://<Portal Server>.sbcounty.gov:7443 -u xxxxx -p xxxxx -a true
Unable to connect to Portal URL : https://<Portal Server>.sbcounty.gov:7443

Has anyone run into this?

We are running ArcGIS Enterprise 10.6.1 on SuSE 12sp3.

Any insight would be appreciated.

Can you connect to the URL with curl on the machine?

Is the certificate CN set to the <Portal Server>.sbcounty.gov?

We cannot connect to the url uing curl. The certificate CN is set to <Portal Server>.sbcounty.gov
