When using HTTPS Send2 V1 may show the following message: The content type text/html; charset=UTF-8 of the response does not match the content type of the binding (text/xml; charset=utf-8).
For proper HTTPS support, Send2 v1 requires changes on the following file:
C:\Program Files (x86)\PerkinElmer\E-Notebook\bin\SendToENotebook.exe.config
Search for:
<security mode="None"></security>
Replace with:
<security mode="Transport"></security>
Save the file and try the connection again.
