A. Operating System, Win10 Version 10.0.18363 Build 18363
B. Graphics Card(s) RTX2070 x2, RTX 2070Super.
C. RAM Capacity 64GB
D. Nvidia driver version 451.77 (updated to this version but still get the error)
E. OctaneRender Standalone version, n/a
F. OctaneRender plugin version 2020.1.4
G. Host application version, including build number if available R20.059
H. A detailed description of the issue and steps to reproduce it - happens on all files. Usually when making a change to the scene while LV is in progress. Eg adding an Octane Object tag. It happens randomly, but often.
I. Copies of the Octane Log window and Console window outputs (full text attached as a file to your post is recommended).

I have the same problem. Rendernode Daemen show
cuda error 201 on device 0: invalid device context could not get memory info render node
Graphic card is rtx 3090. The rendering begins and as soon as the node is connected, everything stops.
Please Help

Please upgrade both Workstation and render-Nodes to 2020.2.4.
You can find it by visiting your personal Downloads area:
https://render.otoy.com/account/download_archive.php

Please download and install also 2020.2.4 Standalone in both machines.
At first start, you will be asked to press the Download button, to automatically install a new cuDNN library to run it correctly:
