New version 13.6, donation version

VPN Tunnel between hosted servers.
Started comparison/mirror 8:30am.
Transfer rate10mbps-50mbps
By 11:30am the transfer rate went to <1mbps

I have restarted both servers.
Restarted both firewalls.
Nothing helps

FFS will not go back to what it did earlier.

Does transferring manually via File Explorer go any faster?
If no, then it's something unrelated to FFS

File Explorer transfers at 35mbps.

Sounds like the connection is fine. What is being transferred when it slows down? If it is a lot of small files vs large contiguous ones, this slowdown isn't unexpected due to the overhead and latency present.

Are you saying older FFS versions did not have the issue?
If you revert & test with older FFS, does speed go back to expected?

Are you testings the same sample data set (even if only a partial thereof) between FFS & Windows Explorer?

It slowed down in a couple hours and won't go back to the earlier speed. Doesn't sound like FFS version was changed

"FFS will not go back to what it did earlier."
I meant that by stopping and restarting FFS, it stayed at <1 kbps, and not what it originally transfered at 10-50mbps. Saturday morning when I started FFS v13.6, it was transferring between 10-50mbps.
It transferred 115GB of 300GB successfully. Then after 3 hours into the transfer, it slowed to < 1kbps.
I have since uninstalled v13.6 and reinstalled v13.0 to see if there would be a difference.
No difference. Both versions are transferring at <1kbps.
I have used FFS for many years. This has been our go to app to migrate data from one hosted server to another. I just used version 13.0 in February to transfer over 1TB of data. It worked perfectly.

I am continuing to use File Explorer transfers. This transfer rate is consistent at 35mbps.

I do not know why FFS will not work.
