1500 Subscribers disappeared, need urgent help

Hello

My website url is (The last great stand – com) … My host recommended me that I should go for SSL certificates and after installing them, My “posts by email” module stopped working so I asked my host to switch me back to normal mode … But now my “posts to email” function is working but I don’t see any subscribers in my wordpress.com account…

Please guide me how I can sort this out

Thanks
