Viber Does not connect to the Internet

I have installed viber at Opensuse leap 15 but it does not connect to the internet. Is there any solution?
Thanks in advance!

Finally i found that viber needs openssl to connect to internet.
Unfortunately i did not know which lib for openssl i should install so i installed all and it worked.
I will be happy if the suse specialist find which exactly is in order to help other users with the same problem.
