Connection Reset by Peer Unity IOS

  deployment, ios, iphone, unity3d, windows

Our team is building an unity based application where backend api are made with php .
After completing the app we exported to andriod and Ios builds and now we have enabled ssl certificate for domain as well .

For Andriod the app works fine with api calls and functionality . But for ios version i.e i phone we are not able to connect to server after checking app logs it shows an error saying connection reset by peer but it works on andriod

Ios seems to work on http but not on https

Can someone guide me like is there any additional change needs to added for ios build in server or in unity

Thanks in advance
