Unix domain Socket not working on Android 9 (API level 28) - c++

Question

I have two android apllication ( client and a server ) that are connected by Unix domain socket on the native level (C++/JNI). Both were built using target API level 27 and were working fine for years. Recently I have upgraded them to API level 28 and now I the client can't connect to the server the connect() function return -1 . If I just change all build dependencies to use lower API levels (<=27) it connects correctly. From what i've read on the behavior changes for Android 9 I don't really know what could cause such a thing. Here is the log that i get from logcat.
com.company.client I/TSOCKET: TSocket::open()
com.company.client I/TSOCKET: TSocket::unix_open()
com.company.client I/TSOCKET: TSocket::openConnection()
com.company.client I/TSOCKET: TSocket::setLinger()
com.company.client I/TSOCKET: TSocket::setNoDelay()
com.company.client I/TSOCKET: TSocket::structlen = static_cast<socklen_t>(sizeof(address)) 110
com.company.client I/TSOCKET: TSocket::openConnection() connect() return -1
I know that API 28 requests run time permissions, and both the service and the app request and get write, read, and internet runtime permissions.
