Im working with an Ignition server that was just set up by another org, so I dont have all the details regarding how the gateway or server is set up. The code below runs flawlessly from the script console, but results in the following error when run from a gateway event script:
[Errno 8] nodename nor servname provided, or not known
import httplib
from base64 import b64encode
url_path = "example/url/path/"
BASE_URL = "example.url.com"
conn = httplib.HTTPSConnection(BASE_URL)
payload = "<xml>"
headers = {
'Authorization': auth_header,
'Content-Type': 'application/xml'
}
# Error occurs on the below line v
conn.request("POST", url_path, body=payload, headers=headers)
res = conn.getresponse()
I looked up the error and saw responses saying that the /etc/host file needs to be modified? I dont see why this would apply. Any ideas?
The full stack trace can be found below. send_req is the function which contains the above code.
