@Jummy, if only one device is having issues submitting the data to the server, then it could be a configuration issue. Could you share a screenshot of the Settings>Server that is having a submission issue and a screenshot of the Settings>Server that does not have a submission issue? These screenshots should help us troubleshoot your issue.

@Kal_Lam Ok, both are here

  1. Couldn’t send submission

  2. Can send submission

They have tried to submit again and this is the error shown:


I am not sure what has caused the problems
