Indian Space Research Organisation or ISRO said the link with the satellite was lost in the third and final stage of its launch, but it did not specify the possible cause of the snag.
"Efforts are underway to establish the link with the satellite," ISRO said on its website.
The satellite was launched on Thursday through an indigenously developed launch vehicle. The GSAT-6A is an advanced mobile communications satellite with a six-metre wide antenna, the biggest used by an ISRO communication satellite.
Once located, the agency should be able to command and take the satellite to its final orbit. If not, the satellite would come down and burn out like any other, an agency official said.
The country is seeking a larger share of the more than $300 billion global space industry as Prime Minister Narendra Modi seeks to project it as a global low-cost provider of services in space.
