Having issues uploading drivers to some remote brokers. Both nwadmn32
& imanager (2.7.4) start the upload, and then errors out or times out.
Nwadmn32 gives an error & imanager shows an http 500 error.

Broker is running on nw65sp8 (edir 8.8.5), connected to me via T-1.
I've uploaded many drivers to this broker before, but recently am
having problems.
