Hi,
I am new be in Moodle. Recently I encounter a problem which I dont know how to resolve it.
I will appreciate anybody which helps me.
Problem:
When I sign-in successfully to moodle & then click "Site Administration", my website doesnt respond until it gives me a 524 Error.
I use Cloudflare for security. Greylisting is Off.
I was working without problems for 3 months but recently face this problem.
Please HELP!
I take it you've seen/read:

What version of Moodle? On what platform? Self-hosted or remotely hosted with whom?
If one is concerned about security of Moodle, been my experience that, as long as one keeps it up to date, runs https (valid cert), and doesn't go 'plugin happy' + install on your own server (depending upon platform) something that is a Web Application Firewall ... mod_security ... (which you can control) then server is pretty secure - and don't think I need CF for such.
2 cent opinion of course,

Hi ken,
Thanks for your quick reply,
Version 3.8.0 on Linux lite speed platform & remotely hosted with cpanel (no whom).
I am so confused why only when clicking on "Site Administration" ????
Cloudflare seems to work without any problem. Only no response from server in a/m situation.
Version 3.8.0 on Linux lite speed platform & remotely hosted with cpanel (no whm).
Translation:? LiteSpeed your web server?
cpanel is not an operating system ... it's only an interface into configuring
the operating system. What is operating system? Ubuntu? Version?
And 3.8.0 is first release of that series ... now 3.8.3 ... suggesting probably
been some fixes to code. So suggest once this is resolved ... or changed ... update the code.
Can you access your cpanel?
cpanel is normally a url with an IP address and port.
Mind sending that info to me via PM in Moodle here? Just the IP address .. am not volunteering to login as you to investigate.
In your config.php file do you have a line like this:
$CFG->admin='admin';
If not add it.
Also in config.php, what's $CFG->wwwroot?
CloudFlare requires you to change your DNS.
https://websiteforstudents.com/how-to-install-moodle-with-apache2-and-cloudflare-cdn-ssl-on-ubuntu-16-04-18-04/
the fully qualfied domain name of server: portal.expertacademy.company
portal.expertacademy.company. 300 IN A 104.31.75.205
portal.expertacademy.company. 300 IN A 104.31.74.205
NetRange: 104.16.0.0 - 104.31.255.255
CIDR: 104.16.0.0/12
NetName: CLOUDFLARENET
Those are as you can see, CloudFlare IP addresses.
The link sent previously suggested reasons and things to try ... those things to try all related to CloudFlare ... not Moodle.
For reference previous link had this item:
"If you need to have scripts that run for longer than around 100 seconds without returning any data to the browser, you can’t run these through Cloudflare. There are a couple of options: Run the scripts via a grey-clouded subdomain or change the script so that it kicks off a long-running background process and quickly returns a status which the browser can poll until the background process has completed, at which point the full response can be returned. This is the way most people do this type of action as keeping HTTP connections open for a long time is unreliable and can be very taxing also."
Don't hack core code ... so in config of php (php.ini) ... there are settings for how long a script can run - set it over 100 seconds.
but note what it says:
This is the way most people do
this type of action as keeping HTTP connections open for a long time is
unreliable and can be very taxing also.
For all reasons above, I wonder if CF Security and Protections are really necessary. Especially if CF has an adverse affect on running a Moodle ... whose security is pretty solid. And like I suggested already, one could add protections with things like mod_security/Securi ... but that depends upon web server running .... LiteSpeed might not be able to use them.

Hi Ken,
Sorry for my bad reply,
This is my exact information for server:
| Hosting Package | Special 5 |
| Server Name | linux4 |
| cPanel Version | 86.0 (build 17) |
| Apache Version | 2.4.43 |
| PHP Version | 5.6.40 |
| MySQL Version | 10.2.31-MariaDB-cll-lve |

Ok, I will update the code. I am afraid of losing data. Please send me any link regarding safe upgrade! I will apreciate.
I checked "$CFG->admin='admin'; " & I had this is config.php.
My $CFG->wwwroot is my domain 'https://portal.expertacademy.company'
Hi Ken,
Yes, I read the link completely,
1. I dont have any long running processes in server but found below errors (snapshot).
2. I dont have any enterprise Cloudflare, only general one. Nothing existed to overload server.
3. Server Health is OK
4. But I put the portal on grey mode for not proxied by cloudflare.
Below screen shows my only cron job which I configured at the beginning of serven installation. Really I am not sure if i have to set more cron jobs.
Also I updated the Moodle to the latest 3.8.3+, but the error remains.
I made the pinfo.php file as instructed in Litespeed support link.
Well, we're making progress .... slowly ..and learning our server environment.
So you've made the pinfo page and can see the settings for time for scripts to run etc. Did you try setting those higher ... defaults are normally low ... like 30 or 60.
Granted those are intended for local server processing, but let's remember how having CF in the middle is supposed to work ... all data goes through CF ... across a network you can't control. According to the page, if CF can't get whatever in 100 seconds ... error 524.
In the error logs shared ... remember, I don't run Litespeed so pardon my dumb question ...
lines do say 'info' but I see the loopback IP address - 127.0.0.1 and a port + APVH
with 404 errors .... file not found ... for 'index.php'.
Huh?
Here's a link to/for Wordpress issues with Litespeed 404's
https://www.basezap.com/solved-404-error-on-wordpress-website-on-litespeed-webserver/
appears Litespeed uses .htaccess files. Got any in your setup?
If so, what does it contain?
Compare what you have to advice given in link above.
Am not saying that will fix this ... just doing some leg work for you.
Cron job ... you've got it pointed to the cron.php script in /admin/ and that should require you to pass a password with the URL. There is a cron.php in /admin/cli/ you should be using.
So it should be if using curl
curl -k https://yoursite/admin/cli/cron.php
Note that uses the web and pointed to /admin/ the area you can't get tol!!! Am wondering if that somehow gets routed to CF and thus is your issue. Cron jobs could run longer than 100 seconds!!!
However, cron job best if running right in/on server ... and just php talking to the cli/cron.php script. Never leaves your server - internal only ... no networking involved thus NO CF!
LIke so ... and so you know it's running I'd do a redirect to a log file you create:
/usr/bin/php /path/to/moodlecode/admin/cli/cron.php > /var/log/moodle-cron.log
rather than the redirect to 'la-la-land'.
Above assumes your server logs are in /var/log/ if not there adjust.
To create the log file, as root user:
touch /var/log/moodle-cron.log
That creates a blank/nothing in it file to which output of the php running of the cron.php script is redirected. Why? If need be one can watch it execute in real time with:
tail -f /var/log/moodle-cron.log
Also /usr/bin/php is a guess ... on a LS system ... you do want the PHP-CLI not PHP used for the web.
Test: /usr/bin/php -v
If you do not see php-cli in output of version, wrong php.
Ok, I've taken this about as far as I can ... don't run litespeed .. don't use cloudflare - so I have NO ... none .. nada .. first hand experience with either.
Best of luck!

Welcome! Did you mention where you were hosted (old hosting)? That info might be useful for others facing similar issue.
'SoS', Ken
Yeah, That was a local host in Iran named "hostiran.net"
Terrible.
