We created and deployed some forms earlier this year and have been collecting data from the users but from last week the forms have not been loading, neither can we upload data from app or deploy new project forms from the Admin console.
Error- 504 Gateway Time-out
Considering that this is a production application, we hope to hear from you as soon as possible.
The screenshot that you shared shows that you were able to deploy your survey form successfully. Could you confirm that you deployed them today!
If you are able to deploy them successfully, you should also be able to submit your data to the server as well as pull blank forms to your android app successfully. Kindly please ensure the settings of your KoBoCollect android app.
