Horizon view client disconnects- horizon 6.2.1

[eviacardozo]

We have been facing this weird issue where ramdom users get disconnected from the VDT and the error is "Unable to connect to server: A connection attempt failed because the connection party did not properly respond after a period of time, or established connection failed because connected host has failed to respond".

ANy kind of help/suggestion will be deeply appreciated.

The logs from Security server are as below:
