Site Not Found after the ssl installation

Hi. After installation of the seritifikat the website ceased to open. The browser shows the message "Not Found The requested URL / was not found on this server.". Removal of the certificate did not solve a problem. I will be grateful for the help. The certificate was PositiveSSL Comodo SSL Certificate

Hello,

I also encountered this issue with the same certificate and received the same message. 

I spent about 2-3 hours trying to figure it out and finally found the following.  It was likely due to some update, because this same server has 2 other domains with SSL certificates and those have never had a problem.

To fix this you'll need to manually update the vhosts files. 

go to /usr/local/apache/conf.d/vhosts/

You'll have 2 files that were recently updated called:
yourdomainname.com.conf
yourdomainname.com.ssl.conf

In each of these files, anywhere you find your "/home/" directory, you need to make sure there is a leading "/".  During the SSL creation, for some reason it is rewriting the home directory as "home/" instead of "/home/".  So just go through and add a leading "/".  There are about 3 occurrences in each file.  The only reason I found this is by doing a line-by-line comparison to vhosts files for my other domains on the same server.

And restart apache after so the changes take effect.

Thanks for council. At present it was busy with change of vps of a hoster and I could not check. On the advice of support service of namecheap.com I established the certificate directly in nginx having edited yourdomainname.com.conf in folder  nginx/conf.d/vhosts/ (perhaps the way is not correct, at present the server does not work and there is no opportunity to check). I prescribed a way to the file of a private key "*.key" and to the file of the certificate "*.bundle". In the .bundle file 3 records were joint. Record root the certificate the sent comodo, and two other records from the yourdomainname_com.ca-bundle file also sent in one archive with the certificate from comodo has to go the first

Спасибо за совет. В данный момент был занят сменой vps хостера и не мог проверить. По совету службы поддержки  namecheap.com я  устанавил сертификат напрямую в nginx отредактировав yourdomainname.com.conf в папке nginx/conf.d/vhosts/ (возможно путь не корректен, в данный момент сервер не работает и нет возможности проверить). Я прописал пути к файлу приватного ключа "*.key" и к файлу сертификата "*.bundle". В файле .bundle были объеденены 3 записи. Первой должна идти запись корневого сертификат присланный comodo, а две остальных записи из файла yourdomainname_com.ca-bundle так же присланный в одном архиве с сертификатом от comodo

edited yourdomainname.com.conf in folder 
/etc/nginx/conf.d/vhosts
