    Hello

    Since this morning I have a problem with the SSL enabled accounts on my server

    After a lot of research, problem occurs with these 3 parameters:

    1: https host with certificate self-signed by cpanel
    2: chrome
    3: specific windows version (maybe android too)

    Problem 1: so with chrome v59 or v58 + windows 10 10.0.15063 + https site, the outcome is:
    This page isn’t working
    didn’t send any data.

    ERR_EMPTY_RESPONSE

    Problem2:
    With android + chrome + https the result is the same

    WORKING:
    all other browsers work fine
    IOS + chrome works fine
    chrome v59 + windows 10.0.14393 works fine

    all https enabled hosts have this problem. you can check with:
    [removed]

    I see NO error on apache log
    I tried disabling mod_security, lfd

    I tried changing the PHP 4.4, 4.6, 7.0

    I don't know what else to do, help please
    Check if your chrome loads on not these hosts, and give me your thoughts

    Thanks

    Are you using Let's Encrypt? We had the same issue a few weeks back. We forced a reinstall of cPanel which somehow fixed the issue.

    I am using AutoSSL, I guess that's Let's Encrypt.

    But why problems occur only with chrome and specific windows versions? was your problem the same?

    Exactly the same. AutoSSL is by default COMODO certificates.

    so your solution was to do a "Force a reinstall even if the system is up to date."?

    Yes. It makes no sense, I know.
    We spent 1 and a half hour making sure that the certificates were indeed correct, and then we just tried forcing the upgrade. We tried countless other things before that didn't solve the issue.

    Hello @4est,

    Have you tried clearing the browser cache in Chrome when testing? If so, could you open a support ticket using the link in my signature so we can take a closer look?

    Thank you.

    I have the exact same problem. Should I submit a ticket or wait for the solution here?

    I've gone so far that I deleted my chrome profile completely, uninstalled chrome, reinstalled 2 versions (v59 and v58)

    The issue is even stranger: I tried on my @home notebook which has windows 10.0.15063 + chrome and there it works.

    another client of mine reported the same problem, he is having it on both of his computers, one is with windows 7!

    I will open a ticket

    I am experiencing the same issue since yesterday. I cannot seem to find any pattern that would explain where the issue is. Most of the users I support have the issue with Windows OS 7/10 + Chrome for all SSL enabled sites that are hosted with us. Internet Explorer works fine, Mozilla Firefox also. Some users do not experience this issue and are able to open the sites that most users with Chrome cannot.

    Requests that end up with the error ERR_EMPTY_RESPONSE do not show in the access or error logs of apache. The only issue that I see in /var/log/apache2/error_log is this:
    [core:notice] [pid 4913:tid 140272935765984] AH00052: child pid 11388 exit signal Illegal instruction (4)

    And it's filling the log file.

    Well it seems that the log entries that are generated in /var/log/apache2/error_log are related to the issue because it makes a new entry every time I make a request that results in ERR_EMPTY_RESPONSE. I've made a strace on the child process that is killed but I am not that knowledgeable to make use of the information provided. I will be more than grateful if someone could point me in the right direction.
    Code:
    [core:notice] [pid 4913:tid 140272935765984] AH00052: child pid 27180 exit signal Illegal instruction (4)

    Hello Everyone!

    Internal case EA-6544 is open to track reports where visiting a domain name over a secure URL results in a "ERR_EMPTY_RESPONSE" error message. This has been reported to happen when using the Chrome web browser on Windows and Android devices.

    The current workaround is to update the "SSL Cipher Suite" value in "WHM >> Service Configuration >> Apache Configuration >> Global Configuration" to the following:

    Code:
    ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS
    If you use a custom cipher list, then you can remove the following ciphers from your custom list as a temporary workaround:

    Code:
    ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305
    I'll monitor the case and update this thread with more information as it becomes available.

    Thank you.

    Michael apparently fixed the problem, at least on my server, so do as he instructed and it should be fine

    Thanks Michael

    Thank you very much Michael! We were working on this since a week now! Does this workaround is to fix a Chrome problem or a server problem?

    Hello,
    New member here..

    We had the same issue on multiple machines, different OS's and versions of Chrome..

    I pulled my hair out, and called the DC, and the SSL provider..
    Some were able to re-produce, and some were not able to.

    This fixed my issue..

    Thank you, thank you Michael..

    It looks to relate to the ea-apache24-mod_ssl RPM included with EasyApache 4, but the internal case is not yet completed. I'll provide more information about the case once it's available.

    Thanks!
