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. ---

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. 🥲 ---
