            #   SSL Protocol Adjustments:
            #   The safe and default but still SSL/TLS standard compliant shutdown
            #   approach is that mod_ssl sends the close notify alert but doesn't wait for
            #   the close notify alert from client. When you need a different shutdown
            #   approach you can use one of the following variables:
            #   o ssl-unclean-shutdown:
            #        This forces an unclean shutdown when the connection is closed, i.e. no
            #        SSL close notify alert is send or allowed to received.  This violates
            #        the SSL/TLS standard but is needed for some brain-dead browsers. Use
            #        this when you receive I/O errors because of the standard approach where
            #        mod_ssl sends the close notify alert.
            #   o ssl-accurate-shutdown:
            #        This forces an accurate shutdown when the connection is closed, i.e. a
            #        SSL close notify alert is send and mod_ssl waits for the close notify
            #        alert of the client. This is 100% SSL/TLS standard compliant, but in
            #        practice often causes hanging connections with brain-dead browsers. Use
            #        this only for browsers where you know that their SSL implementation
            #        works correctly.
            #   Notice: Most problems of broken clients are also related to the HTTP
            #   keep-alive facility, so you usually additionally want to disable
            #   keep-alive for those clients, too. Use variable "nokeepalive" for this.
            #   Similarly, one has to force some clients to use HTTP/1.0 to workaround
            #   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
            #   "force-response-1.0" for this.
            BrowserMatch "MSIE [2-6]" \
                            nokeepalive ssl-unclean-shutdown \
                            downgrade-1.0 force-response-1.0
            # MSIE 7 and newer should be able to use keepalive
            BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown


Is that the exact command as you ran it ? or have you retyped it here ( and possibly got a mistake in it).

For some reason it's trying to go to rather than (with the "/" in there after your domain name.

In your command;

sudo certbot-auto ceronly --webroot -w /usr/share/drupal7/ -d

you have "ceronly" which should be "certonly" although that in itself won't cause the problem you are seeing - I'm just wondering of there were other mistakes in that line.

Right, the slash is missing from this line:

Redirect "/" ""

should be:

Redirect "/" ""

Also note that Drupal 7 currently requires a patch to make it compatible with webroot authentication, see (this should hopefully be fixed in the next update).


Transliteration here:

Thanks. the comment is clear on this link. I put the patch under my directory, /etc/drupal/7/. But, the git tool I am not fairly good at git. I understand the code modification which there are 7 lines from starting on line 3 and 7 lines from starting on line 89. May I copy and past directly instead of git this tool? Because of that I got some error issues when I used "git apply ", hence I intend to paste code instantly. Will this method affect the future update? What I have done is to backup htaccess to be htaccess.bak. Then, I open it with vi and check where the code exist on which location exactly. Actually, code is on line 6 and line 85. So, I mark with # on line 6 and 84. And I add new code on line 7 and line 86. The next step I reload and restart apache before executing “sudo certbot-auto certonly --webroot -w /usr/share/drupal7/ -d”. It isn’t ok initially and give some query time out information which I refer goole to get known about the reason. (i.e. It is a mater not on my site. Just try and run again.) Finally, I implement “sudo certbot-auto certonly --webroot -w /usr/share/drupal7/ -d -d” (I add -d and got worked.

Next time you update Drupal core, you should check the .htaccess file to see if those lines are still changed, and if not, change them again manually as you have done here.

Alternatively you could try using the patch utility which works in some situations where git apply does not. has more information.
