Comsol with matlab error on HPC cluster

Dear All,
I run my comsol models with matlab on HPC cluster which have CentOS Linux installed on it. I use the following command for starting Comsol server on HPC
comsol mphserver &
This command starts Comsol server successfully but when I start connecting matlab to it by the following commmand:
matlab -nodesktop -nosplash -r "mphstart; mymfile.m; exit",
there appears an error which say: "Comsol server must run before calling mphstart", while I am sure about starting Comsol server, even when I try to start Comsol with Matlab by the command:
comsol mphserver matlab
server starts and runs Matlab but a confusing java error occurred and further processing is blocked.
FYI, I use Comsol version 5.3, It is interesting to inform you that everything is OK on my laptop with Windows 7. These errors occurs when I try to perform my simulations on HPC.
Any suggestions and helps are appreciated, Thanks,

Hi Robert
It seems as if your Matlab session can't see your session where Comsol Multiphysics Server is running. Are you running these on the same computer? Does the computer have a firewall?
Supplying mphstart with the server name and port number often helps.
