hello, i'm new to orthanc and i want to connection two orthanc servers through the internet, is http connection enough?

What do you mean "is http connection enough"?

If your concern is security, you should use HTTPS; Please read the Orthanc Book:

i wanted to know if it's an obligation to use https when the servers are not on the same lan, here is my configuration, the ip address where the the other orthanc is installed is 37.170.4.120 on the port 8042,since on the rest api the only modification to make is to add an entry in the "Orthancpeers", i don't know what else to do, i can't connect to the second orthanc, can you please tell me what i'm missing, thank you

regards

You don't have to go through https, http is technically fine, even though not secured, so we would not advise you to go through http over the Internet, especially not if you are transferring real patient un-anonymized data.

Instead of a peer connection between your two Orthanc servers, you could setup a DICOMweb connection thanks to the DICOMweb plugin (https://www.orthanc-server.com/static.php?page=dicomweb).

Anyway, have you tested the connectivity from one server to the other?

What's the output of a curl -v http://37.170.4.120:8042 command from your first Orthanc server?
