Hi stevezemlicka,
Pity you had to set up everything anew, but nice that you are up to date 
With a direct connection, 200 MB is reached within seconds, is it not? How long does it take before giving a timeout?
There are a few more timeouts that may be set, @xGuys listed quite a few in a similar post to yours today.
As with a mere 200 MB you probably are not hitting a file size limit, your topic title could attract more attention if it mentioned “timeout” instead of “size limit”. Maybe you could change it after concluding it is not dependent on the size of the files.
