Description:
Hi All,

I'm running NGINX+SSL WordPress VM on Google Cloud. I tried to install SSL and I belive during that process some how things went wrong. Initially, I got I below error in nginx.log file:

2019/11/09 02:33:21 [error] 1536#0: *30 FastCGI sent in stderr: "PHP message: PHP Warning: require_once(/opt/bitnami/apps/wordpress/htdocs/wp-config.php): failed to open stream: Permission denied in /opt/bitnami/apps/wordpress/htdocs/wp-load.php on line 37PHP message: PHP Fatal error: require_once(): Failed opening required '/opt/bitnami/apps/wordpress/htdocs/wp-config.php' (include_path='.:/opt/bitnami/php/lib/php') in /opt/bitnami/apps/wordpress/htdocs/wp-load.php on line 37" while reading response header from upstream, client: 108.162.250.40, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/opt/bitnami/php/var/run/www.sock:", host: "www.tripekak.com"

Then I followed guide in below link to fix it :

Although I don't get the previous error anymore, I do get following error now in nginx error.log file

2019/11/09 03:38:33 [error] 5041#0: *1 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 101.116.47.51, server: localhost, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://unix:/opt/bitnami/php/var/run/www.sock", host: "34.94.107.148", referrer: "https://34.94.107.148/"

Can you please help me to fix this issue. I'm new to WordPress technical and appreciate your support.

Hi all,

I was able to solve the issue for now and get the site back again.

I think the issue was related to installing Lets encrypt SSL certificate. The installation of SSL certificate had not proceeded correctly due to CloudFlare - you can read more here - https://community.bitnami.com/t/letsencrypt-ssl-failure-on-gcp-cannot-negotiate-alpn-protocol/65755

After doing more research on bitnami troubleshooting guides I ran below command

sudo rm -rf /opt/bitnami/letsencrypt

I'm planning to follow the steps to remove CloudFlare as per this link before installing Lets encrypt certificate and then connect CloudFlare again.

If anyone can give some further beneficial advise kindly let me know.

Hi @DonHenry,

I just found that PHP is throwing the next error message

[09-Nov-2019 04:25:43] WARNING: [pool www] server reached max_children setting (5), consider raising it

I also found that you have a wp-vcd.php file in your installation. We recently received many support requests related to WordPress' sites that went down without any apparent reason. Because of that, we published this security notice in our documentation, could you please ensure your site is secure?

The rest of users are running into similar issues.
