Hello guys, We use the AXC F 2152 in combination with a 3G/4G router. We use portforwarding to reach the HMI, but with the AXC F 2152 we’ve problems to reach the HMI through portforwarding. The forwarding connects to port 443 of the PLC. I get to see the HMI background, but there are problems to load the variables. I see then the errormessage: A connection with the PLC could not be established. Retrying in X seconds It seems that the API connection can’t be established: hmiapp.min.js:133 [Tue Feb 04 2020 10:46:36 GMT+0100 (Midden-Europese standaardtijd)] ERROR: Base Data Access service’s XML HTTP Request failed for command ‘ReadGroup’ with status code ‘0’ and status text ‘’.
