While you were offline configuring the hardware, security, and web server for your s7-1200, did you make sure user was configured as well and granted rights to access via web as admin? 3deviopl Did anyone managed to run this (jsonrpc) on 1200? in mentioned below YTube video some guys confirmed this feature works: As of V4.5 Firmware of S7-1200 and TIA Portal V17 this feature is also functional in S7-1200.

While you were offline configuring the hardware, security, and web server for your s7-1200, did you make sure user was configured as well and granted rights to access via web as admin?
