We have implemented a remote monitoring solution for PV systems in rural areas in Sub-Sahara Africa. We use a cloud of the EU Central region (https://eu-central-1-1.aws.cloud2.influxdata.com) as we have developed the system in Europe where it worked nicely. Now we tried to send data to the system from systems in Ethiopia (different locations, different SIM cards, internet generally OK). However, we fail to connect to the cloud.
We use an Arduino to send data. Command:
HTTPS_PORT = 443
HOST_NAME = “eu-central-1-1.aws.cloud2.influxdata.com”
What could be the reason for that? Is there a mechanism that blocks a connection in place?
Any hint is much appreciated.
