Hi, I am trying to execute a post request( sending files using rest API). I see that when I execute the request from localhost it's giving me a status code of 200 where as when I execute the same code from another system's Localhost i am getting 502 bad gateway error. May I know what difference the two localhost gateway could have. They're of the same versions.
I am using httplib module to perform the post request.
Thanks.
It's probably something unique to your network, like a misconfigured proxy or firewall or some other network appliance in the middle. You'll probably need to work with your IT department.
I've both the ignition gateway installed in my personal laptop and official laptop.
This. Something is blocking the traffic on one machine. Typically an IT-enforced firewall or security proxy.
Hi @pturmel , I see that when i am sending a file below 50kb ,the request gives a success status 200 , where as if it's above 50kb it's giving a 502.
Then something along the way, or the target server, doesn't like posts that large. 
You need to be looking at logging on the other end of this connection.
I assumed it to be the target server's issue, but then when i try it from another laptop where I've the same version of ignition installed. I am able to send the same file from there and it's 200 again. 
You really need to talk to your IT group.
okay @pturmel thank you
