EMD upload error: uploadXMLFiles skipped :: OMS version not checked yet

I ran into an issue where agent was not uploading the xmls to the OMS server. emctl upload fails with the error "EMD upload error: uploadXMLFiles skipped :: OMS version not checked yet..."

To resolve the issue try the following.
Check if the host is able to communicate with the OMS by using telnet as mentioned below. If you punch in "^]" escape sequence, you will receive Apache version that OMS is running currently on the port 4890.

$ telnet testsrvoms.msudhan.com 4890
Trying xx.xx.xx.xx...
Connected to testsrvoms.msudhan.com.
Escape character is '^]'.
