Sendbird notification test results in ssl error

My notifications was working fine but now, throws ssl eof error, what can be causing this ?
I am using v3 chat sdk

@festersson Sorry for tagging, but I really could not figure out exact issue.

No idea, but make sure that the notifications certificate you are adding is created/exported properly and the same is true for the certificate setup in the sendbird dashboard

Certificates are correct, I redone it. and everything is correct. I only receive first notification when I restart the notification feature. after that it just results, first in connection reset by peer and than in ssl error.
