Hello everybody,
since yesterday (2021-09-29) when I try to open the roundcube login screen on an iOS device I got the error message: ERR_INVALID_RESPONSE in Chrome or "Unable to parse response" in Safari.
But on every other device (Microsoft, Android) the site works fine.
Anybody able to help me. The site I try to open is: https://webmail.net4you.net
Thanks in advance

Anybody who can test the URL with his iOS device and let me know whether the sites work for him or not?
With kind regards

The problem still occurs.
Anybody able to help me with this?

In the Apple-Forum I got the message that I should stick with RoundCube because it might be a specific error of the RoundCube page and not a general problem with the safari rendering engine.
So I'm back here asking for help.
Anybody able to help me?
Thanks in advance

I found out, that it seems to be related to the protocol. On an Apple device when i use curl with http/1.1 the site will be delivered but when i try it with http2 no response will be received.
Could that be a problem with the RoundCube-System?
Can you analyze this?
With kind regards

That would be a problem with the web server not with Roundcube.
-
But how could it be a problem with the server, when all other OSs and browser can access the site without problem even when HTTP/2 is enabled. Only in connection with Apple-OS and http/2 there is a problem.

Safari is the new IE 6 not following standards and generously not working very well. I see a lot of Safari only problems now a days. HTTP/2 is handled at the web server layer (Apache/Nginx) not at the Roundcube level so that would be where the change would be needed.

Hi SKAero,
in this case we keep HTTP/2 switched off for this roundcube installation, then also safari can handle the login page ;)
