Connection from Ethiopia / Africa (with Arduino)

Dear all,

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 ( 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:

sslClient.connect(HOST_NAME, HTTPS_PORT)


What could be the reason for that? Is there a mechanism that blocks a connection in place?

Any hint is much appreciated.


Hello @ethiopian,
That’s super cool! I love learning about solar projects.
I’m not too familiar with sslClient

Can you try querying with cURL?

Dear @Anaisdg, thanks a lot for your answer. I will try it and let you know how it goes.
