Hello,
We are using Nginx as a proxy server and a SSO authentication for the ThingWorx setup.
Also we have a ThingWorx Connection Server After Proxy server to be able to connect more number of Edge Devices.
We are able to connect only around 3800-4000 edge devices maximum.
And we are seeing below Errors in Nginx error logs.
2021/10/26 18:02:32 [error] 2384#2384: *1 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 123.21.21.122, server: server.com, request: "POST /Thingworx/Things/ApplicationAThing/Services/ButtonVisible?Accept=application%2Fjson-compressed&_twsr=1&Content-Type=application%2Fjson HTTP/1.1", upstream:

Any guides as to why these errors are appearing and what they are indicating.
Any inputs would be very helpful.
Thanks and Regards,
