I am looking for an expert in Flask/ to help troubleshoot an issue we are having with an app we are setting up. We are attempting to connect a Flask/ app to an iOS app coded in Swift and the emitted messages are not receiving responses from the server. Our localhost server installs work and send/receive socket responses but when working with our production server it is not working. The production server is on Amazon EC2 and we have tried many different approaches so we have a lot of documentation on our attempts and what has and hasn't worked. I get the sense it is something relatively small since it works fine locally (possibly a module or something similar not working correctly). My budget of $250 for some basic consulting. We are flexible if we uncover a larger problem once looking into it but really need to move quickly to at least expose the problem. We are looking for the best EXPERTS in this field and are willing to pay well if you can knock this out quickly. Please do not apply if you have not worked in this type of environment in the past. Thanks!
