Hi Harini, I opened a new thread for this to make it easier to follow up on this subject. I just tested my Push Server and iOS just worked fine. Here are a few questions: * Did you upload the correct .p12 file for the iOS variant? * Or did you replace a development cert with a production cert ? * Did it work a few days ago? * Did you try to reboot the instance via the openshift UI ?
