hi, i am developing a project through nod-red on raspberry pi. raspberry pi connects to internet through router rut955.
I can't send the emails from node-red when rut955 is connected to the internet through the sim. I tried to run the same program on an amazon ec2 and it works, so the problem is not the program, it will be due to rout955, has anyone encountered the same problem as me? thank you so much for the support.
