Does iOS client not support tls?

[Laisky]

Your Rocket.Chat version:

• server: v0.19 with letsenctypt certification,
• iOS client: v2.2.2

My rocket.chat server is https://chat.laisky.com/ ,support tls1.0 - tls1.2

But I can not load the login page after connect to the server, it retry again and again.

I had tried to reset my device's network setting, and reinstalled the app, but nothing help.

Both on iPhone and iPad got the same problem. OSX client works quiet well.

The SSL looks good

Since letsenctypt is rather new, I wonder if there is come root certificate missing.

Let me me do some debugging from my side and get back to you.

[Laisky]

thanks for your response.

Browser, Windows client and OSX client is ok, the problem only happened on iOS client.

What version of iPhone and iOS?

In my deployment letsencrypt working perfectly, so it's not cert issue, even not cipher mismatch.
Check that your ROOT_URL environment variable value is https://chat.laisky.com/, i had almost the same issue when started rocket with http:// after test moved to https:// but i didn't change ROOT_URL value to indicate this.

[engelgabriel]

Thats a good point

[Laisky]

Change the ROOT_URL from https://chat.laisky.com/ to https://chat.laisky.com solve the problem.

thanks very much for your help, it's my fault.

I have this error for both iOS and Android app, webinterface working fine.
And if you're using the snap you're stucked now because you can't change the ROOT_URL.
see #4971

I changed to manual installation with ubuntu, set the proper ROOT_URL, but I still cannot connect with iOS or Android over HTTPS, only HTTP is working.

My certificate is self signed, but native OSX app is working fine as well, just get an error the first time when I try to connect.
