cannot use PBX-Network connector anymore, likely due to new certificates in use

What steps will reproduce the problem?
1. enter a text and try to send, or
2. try to update balance
3.

What is the expected output? What do you see instead?

balance shown or text send. Instead I see a small message that certificate 
validation and thus connection failed.

What version of the product are you using? "Last" is not appropriate. Make
sure you tell at least which app you are using. On what operating system?
WebSMS 4.8, WebSMS Connector: PBX-Networks 1.1, Samsung S4 Mini with Android 
4.2.2

Please provide any additional information below.
