HP System Managment HomePage timeout error

[osamamansoor]

Hi every one,

I am new in HP community and first time using this community for my quries.

I have HP DL380p Gen8 on which i installed Windows Server 2012R2 , i install HP System Managment but it when i click on  HP System Managment HomePage and provide my login id and password after that the response time is very very slow and also pop up some SNMP related error however my i reset in to default setting of SNMP but still error occurs 

A timeout occured while loading data for the HP System Managment HomePage which may result in missing or incomplete information.Please ensure that the various agents configuration is correct.One common error is around setting SNMP community strings and having at least one read/write string specified.for additional information on how to discover which components may be causing the timeout , see the HP system Management homepage log and the HP system Management user guide troubleshooting section.
