I am making a post request and it has been done successfully on reqbin but when I use the code in my script, even if I copy and paste exactly, it doesn't work. I'm getting a 500 status on these and if I try other languages i get a 301. But I don't know what exactly is going on or what I'm missing.
expected response:
```{
"data": {
"txGasUnits": 132500,
"returnMessage": "",
"smartContractResults": null
},
"error": "",
"code": "successful"
}```
response from python:
b'{"data":null,"error":"transaction not found","code":"internal_issue"}
response from php and bash:
```<html>
<head><title>301 Moved Permanently</title></head>
<body bgcolor="white">
<center><h1>301 Moved Permanently</h1></center>
<hr><center>nginx/1.14.0 (Ubuntu)</center>

resp = requests.post(url, headers=headers, data=data)
print(resp.status_code)
I added the php and bash just to show that other code snippets also failed, and in a different way, incase that may be relevent. I tried my own code and had the same result. Then when I used reqbin i got it to succeed, and then after struggling with it a bit I simply copied the code they generated and tried that precisely but it still didn't work. What could be the error?
The mistake is in the URL you're using. Instead of
http://, usehttps://and it'll work.As a rule of thumb, try to use
httpsto interface with any service Elrond exposes, as that's the secure and supported way to go. Thehttpport might be dead or straight up closed.
