When installing/updating Citrix Workspace app this morning I was still getting the error that has been reported.

Here is the log of the failed attempt:

When looking between version 10.7 and 10.8Beta the entry for citrixworkspaceapp is exactly the same.

    ;;

When checking on Slack I found the fix mentioned by @dan-snelson about adding curlOptions to the entry which it has been in 10.7 & 10.8Beta. But only the curlOptions configuration portion was added, but it was not added to:
htmlDocument=$(curl -s -L $urlToParse)
by changing it to
htmlDocument=$(curl -s -L $urlToParse $curlOptions)

This fixed the port number issue for downloading the DMG file for Citrix Workspace app.

Sorry if this a duplicate submission on this error I could not find another active one.
