I am getting this error
"PKIX path building failed "
when i make Rest call to web-service. Earlier it was working fine, but recently some certificate expired from web-service side and this error started coming.
When I contacted WS team , they said they install the certificate again and it should work fine.
though they installed the certificate , I am still getting the error.
One more thing, when I am making HTTP call instead of HTTPS , i don't get the error but response is also not coming. I am getting blank response.
