APP worked, now I get connection closed, blank (white screen), is it CERT issue?

[Jan]

Hello everyone, I already have app, but it stopped working.
I have generic code in my app "Unknown Failure", found where that code is, and it is custom message, not one from Betfair.
My Android app makes login over: "https://identitysso.betfair.com/api/login"
Then sends json to: https://developers.betfair.com/api.b...ng/json-rpc/v1
Then I try to list some events:
{"method":"SportsAPING/v1.0/listCompetitions","params":{"filter":{"marketStart Time":{"to":"2019-01-28T12:19:04.461Z"},"eventTypeIds":["2"],"marketTypeCodes":["MATCH_ODDS"]}},"id":1}
D/OkHttp: --> END POST (181-byte body)
I/System.out: [socket][1] connection developers.betfair.com/84.20.208.121:443;LocalPort=-1(1000000)
I/System.out: [socket][/192.168.1.5:42722] connected
But that's it, next screen should be events, but I don't get them.
I/System.out: close [socket][/192.168.1.5:42722]
D/OkHttp: <-- HTTP FAILED: javax.net.ssl.SSLPeerUnverifiedException: Hostname developers.betfair.com not verified:

Is it because of certificate?
I didn't see any announcement that I have to use cert?

I believe there was a change to the non-interactive login. Might that be the problem?

Yes if that happened, than it's for sure problem, but why it doesnt say in release that they changed way people are logged in, I keep getting:
HTTP FAILED: javax.net.ssl.SSLPeerUnverifiedException: Hostname developers.betfair.com not verified:
Even for delayed (free api login)
Can somebody help me with how to send certificate, I made cert on my mac, uploaded to my betfair acc, but not sure how to pass it in Java to betfair.

I did check connection and certificate over MAC Terminal it is working fine, I get sucess.
{"sessionToken":".............=","loginStatus":"SU CCESS"}
But not sure how to implement it to JAVA, if there is someone who can help, that would be awesome
