Hello, MappCockpit works in simulation, but not on the PLC, where it says “site can’t be reached” in the browser. I have just changed from ACP10 to mappMotion and have tried to implement mappCockpit to test the servos. I reach the site through Tools → mapp Cockpit. [image] PLC: X20EM1611 AS: 6…

I figured it out. I was connected to the PLC remotely through VPN and when I tested with the cable it worked. Adding the correct port in the VPN made it work remotely as well. Thanks to all of you for trying to figure it out for me! Almida

Hi @Almida , Can you open SDM when the simulation is off? Thanks Ciao Valerio

Hi Valerio, Yes, the SDM works.

I had actually already found that thread and tested the time sync. After syncing it still differs 1 second, if that matters. It didn’t make a difference unfortunately, anyhow.

ok, second idea (I got input from expert): Maybe the port 8084 is already in use on your PC. Could you try to configure another unused port? [image] Have you already used the command “netstat -a”? it will help you ======== Could you upload System Dump? We should see some errors… Ciao Valerio …

Doesn’t that just matter if it doesn’t work on my PC? It works on the PC with 8084 but not connected to the PLC. One thing I notice is that in the help, and in your picture here, there is a SLL configuration that is not available in my project, that box only comes up empty, but I don’t know if tha…

Hi @Almida [image] Almida de Val: It only works with HTTP and not HTTPS in simulation. Did you install your certificate in Windows already? [image] [image] [image] Don’t forget to add in your certificate the URI, DNS and IP Adresse. [image]

Have you checked that your browser doesn’t redirect to a https website by default? Instead of just entering the IP in the adress bar, add http:// to the beginning. The port itself doesn’t help with a redirect to https or http.

[image] Valerio Manenti: Can you see this Login Popup window? or you don’t see that and immediately you have the message “This site can’t be reached?” I don’t reach the login window at all, only get the “this site can’t be reached” directly. In simulation I got the login window and could log …
