cuGraphicsGLRegisterBuffer failed with error(219) gst_eglglessink_cuda_init texture = 1

Can you refer to Nveglglessink fails with CUDA error 219 in ds5.0 and try the solution?

I do not have access to physical monitor as this is AWS. Main reason is due to SSH access. I tried with xhost + and export Display=“localhostip”:0.0
Kindly help
