Spark File Transfers From Bria 3 or 4 Fail

Good Day we are running the following setup:

Elastix 2.4

Open Fire 3.71

We are using Brea 3 and 4 as well as spark 2.7.2

instant messenger works as expected without any issues

the problem we are having is with File Transfers

when sending a file from SPark to bria3 or 4 works fine

when doing it in reverse from Bria3 or 4 to Spark the transfer starts sparke receives the transfer request when end user approves it 1 send later error pops up saying the file transfer was cancelled

Does anyone have a suggestion ?

Thank you
