I have a problem connecting to my Rocket.Chat instance via iOS-App.
It is working via Safari-Browser, via Android-app and via Windows-Client.
The certificate is not self signed and the full cert-Chain is available.
For those who want to try: server.domain.tld [Edit: removed after solving of problem]
I even tried to import all the Certs in the chain to the iPhone, but its still not working…
I do not know what to do…
can someone help please.
