[MAYBE SOLVED] HTTPS site losing PHP connection overnight! - John_Betong - 03-01-2021
I have an Ubuntu VPS server with over a dozen sites and recently added a new free domain with CI4. The site still opens a index.html but PHP is not working?
For the past couple of days I have had to reinstall the Certbot certificate and that cured the problem.
Now the PHP is giving the following error report:
This site can’t be reached
MyNewSite.com unexpectedly closed the connection.
Try:
- Checking the connection
Any suggestions as to where I should start looking for the problem?
RE: HTTPS site losing PHP connection overnight! - John_Betong - 03-04-2021
I think I have found the problem now that I have added declare(strict_types=1); to every system PHP file:
Quote:( ! ) Fatal error: Uncaught TypeError: filter_var(): Argument #3 ($options) must be of type array|int, null given in /var/www/ci4-strict.tk/system/HTTP/RequestTrait.php on line 341
The following KLUDGE fixes the problem:
File: /system/HTTP/RequestTrait.php on line 341
PHP Code:
# KLUDGE - 2021-03-05
$flags = NULL ?: 0;
return filter_var($value, $filter, $flags);
}// public function fetchGlobal($method, $index = null, $filter = null, $flags = null)
Usually the site has previously gone down overnight and I will check again tomorrow to ensure the KLUDGE cures the problem... watch this space

In the latest version CI 4.1.1 line 341 //--------------------------------------------------------------------
declare(strict_types=1); - Strict type matching. Without this, null will not throw errors.

@iReddis,
> declare(strict_types=1); - Strict type matching. Without this, null will not throw errors.
That was why I added strict_types. The site was going down and there were no errors being reported!
Where should I have started looking for problems without any errors logged?
Update:
The site did not go down last night I am delighted to say

I may be wrong, but it seems to me that you have a problem on the path from the browser to the server. But not including the framework.
Set environment as development in the .env file.
See server logs.

I set the online .env file development and managed to get the error_logs to render...
I prefer using strict_types=1 and will raise some Pull Requests where necessary.

The server was still going down overnight but at least errors were reported thanks to strict_types=1;
After well over a week I bit the bullet and purged apache2 and a2dismod php7.4... then reinstalled apache2 and php8.0. It took a while but eventually after installing a2enmod missing apache2 modules and using certbot to reinstall about sixteen domains the new domain was still going down overnight!!!!!
Fortunately I had a spare domain (which is seldom used) and swapped all the content from the new domain to the spare domain and the new domain has not gone down!!!
