Hello,

We have a customer who has a Form that users are trying to submit but get a Message: An unexpected error has occurred. [LFF502-UnexpectedError] when submitting the Form and they have to reload the Form and re-enter all of the information, in order for the submission to go through.

The Form has approximately 20 Fields that need to have data re-entered.

Also the majority of the users are submitting this form via a Tablet and using LFMobileDroid as the Browser.

I am not sure if we need to edit any timeout setting in the Forms Web.Config or RoutingEngineServiceHost.exe.Config, possibly, since they are submitting this via a Tablet Data Connection.

Full Error Message Below:
