Teamviewer Transfer Speed is slow, sometimes

Recently I have had a problem with slow file transfer speeds. I am using Version 14 with the latest update.

I use TM for my remote telescope. After a night of collecting data, I login to the system and usually transfer about 1 GB of data. That should take only a couple of minutes. But now it usually, but not always, takes over an hour. I thought it was a network issue, but others on the same network are not having the same problem. Although I don't know what kind of file transfer utility they are using.

the last couple of days I have experimented with logging off and logging on and then doing the file transfer. For some unknown reason that seems to solve the problem, and the file transfer proceeds as it should. This makes it sound like a setup issue with TM.

If anyone has an idea of what is going on, please let me know. Advise would be appreciated.
