First you should implement an exception handling and log it, for example: try //Get Command ... except on E: EIdHTTPProtocolException do Log('HTTP Error: ' + E.Message + ' (Code: ' + IntToStr(E.ErrorCode) + ')'); on E: EIdSocketError do Log('Socket Error: ' + E.Message + ' (Code: ' + IntToStr(E.LastError) + ')'); on E: Exception do Log('General Error: ' + E.ClassName + ' - ' + E.Message); end;

You should not use Delphi XE7 for Android 12. XE7 supports Android <= 4.4. https://docwiki.embarcadero.com/PlatformStatus/en/Main_Page

For us TS Plus works great.

I think tsplus webserver could do the job ...

The default behavior is the same since delphi 4, but since a few versions the optional "OldCreateOrder" property is ignored: https://docwiki.embarcadero.com/Libraries/Athens/en/System.Classes.TDataModule.OldCreateOrder

You could also try to create a select query and assign it to conection first and let it open until everything was done. This could avoid to the connection to the pool and unassign it.

How looks the code for the creation of the query?

What is the setting for Connection.ResourceOptions.KeepConnection ?

You could also try to enable ExtendedMetaData for connection.

What are your connection settings?

Do you have in your HTML part something like <img src="cid:FileName"> ?

You are using a Generator and a trigger? I thought you were using "generated by default as identity" for field in create table.

In Firebird 4 something like this could work: UPDATE OR INSERT INTO ESTDTL (EST_ID, ESTDTL_ID, CSC_ID, ESTDTLDSC, CSTPLS, GSTINC, GSTPCT, QTYCLC, QTY, CST, GST, SLE, VAL) OVERRIDING USER VALUE VALUES (:NEW_EST_ID, coalesce(:NEW_ESTDTL_ID, -1), :NEW_CSC_ID, :NEW_ESTDTLDSC, :NEW_CSTPLS, :NEW_GSTINC, :NEW_GSTPCT, :NEW_QTYCLC, :NEW_QTY, :NEW_CST, :NEW_GST, :NEW_SLE, :NEW_VAL) MATCHING (EST_ID, ESTDTL_ID) RETURNING EST_ID, ESTDTL_ID

The images are not visible to me. And what was the solution for your initial issue?

Therefore I have used MATCHING (EST_ID, ESTDTLDSC) (And maybe additional fields), because ID is created by DB after post. But maybe there is another solution using the id field...
