Page no load - 503 Service unavailble

[javierlechuXD]

Hello everyone

My problem is that from time to time my web stops working

Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.

But after a few minutes it will be online again but the bot is off I think the problem occurs when the bot has to work or do something

I do not know if the problem may be because I have not configured the Cron Jobs in Cpanel

/10 * sudo -u www-data php /path/to/your/websever/path/to/Ranksystem/worker.php check >/dev/null 2>&1

How should I configure it to /Estadisticas.gameflix.es/worker.php

that's OK? sudo -u www-data php /home/gameflix/Estadisticas.gameflix.es/worker.php check >/dev/null 2>&1

or

sudo -u /opt/alt/php71/usr/bin/php /home/gameflix/Estadisticas.gameflix.es/worker.php check >/dev/null 2>&1

actual configuration: https://i.gyazo.com/a1a16ebb84f1107de3b685eab857822b.png

Currently still with the same error

I have checked that the bot stops working when there is a change or a user enters the server. The page stops working too

[Shad86]

Hello,

If I see that right, you're using a webspace?

how does the config look in "other", is hashing enabled in your config?

If it mostly happen if a user joins, it could maybe that this is to much for the webserver, so try disable it and look if it still happens.

"if there is a change" <- What do you mean with it? That could be everything.

If that is so, then you have to consider to change another setting as this is a common issue with rented webspaces, the most excuse is, that the load is too high and that the service is getting terminated.

So activate the "Query Slowmode" in the Webinterface under TeamSpeak and set it to a "high delay"

This will reduce the load and could result in an improvement.

regards

javierlechuXD, we have written yesterday on our public teamspeak server. I do not understand, you are opening a ticket now.

We host the Ranksystem for you. Our page is available and have no 503 server error. You are using your own domain address and do a redirect. Your redirect is the problem, not the Ranksystem. https://ts-n.net/host/rs/79/stats/

As already written yesterday, you need to correct this. Perhaps your hoster could help you with.

[javierlechuXD]

The host of the web asks me what is the script that the bot uses to work

He asks me if it's the next /worker.php

Surely you want to know to grant permissions to that Script on your server

I greatly appreciate the host that you gave me, We are currently using it and it works well for our main server, But we want to have a host on our server to test with our secondary TS3 server

[javierlechuXD]

According to the host of my website, the bot gives security errors in cpanel since it is considered as suspicious process

[Newcomer1989]

The Ranksystem is describes here: https://ts-n.net/ranksystem.php#howto

According to the host of my website, the bot gives security errors in cpanel since it is considered as suspicious process

Which errors? Please share us more informations. 1) We need to know, what you have done and where are you.. 2) Where does the error occurs? 3) Share us the exact error message

[JoniVR]

Same thing here, I've checked the ranksystem.log file for anything but it doesn't look like it.

I do remember enabling the "hash IP addresses" recently.. Since I couldn't get into the settings panel (page was unreachable of course), I disabled the setting through the SQL db with the command:

[ts3_ranksystem]> update config set iphash = 0;

I then tried restarting it by running: php worker.php restart But that didn't help either. The other parts of the site are still working fine. Any suggestions? Am I missing something?

My server is also quite high-end and doesn't have a lot of load, so I honestly don't think it's a performance issue.

[Newcomer1989]

Can you please share us your webserver log in that moment, you are entering the webinterface.

You get this error permanent? Which site you like to enter? The webinterface?

[JoniVR]

Yes, this error stays on, whatever I do, the worker.php is running as usual and the log files don't report anything special. I get it on the entire ranksystem (as far as I'm aware) but nothing else is affected (even though it's running on the same server).

You can check out the pages for yourself: https://vitaltactic.be/ranksystem/

Main site is still up and running: https://vitaltactic.be/

Let me know if you want me to provide anything else (logs, specific files, ...)

[Newcomer1989]

We need the part of the webserver log!

[JoniVR]

Alright, I'm sorry I misunderstood your last comment.

So the access.log from apache doesn't show anything interesting except for which requests where made and it really only contains data which I don't feel like I need or want to share here. It's basically all the GET requests without anything useful in it.

here's a line from error.log that appears constantly (also apache2 logs) and might be interesting:

I removed some of the Download avatar lines from that because it would get really long, but I double checked nothing else was in there.

Let me know if you need anything else.

[JoniVR]

Managed to get it back up end running by restarting that service: sudo service php7.2-fpm restart and then manually restarting the worker.php again.

[Newcomer1989]

Ok, the decisive message is this:

Sat Jan 05 23:00:13.929312 2019] [proxy_fcgi:error] [pid 28329] [client ] AH01079: failed to make connection to backend: httpd-UDS [Sat Jan 05 23:01:42.293760 2019] [proxy:error] [pid 25976] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /run/php/php7.2-fpm.sock (*) failed

That seems to be not a problem with the Ranksystem. That looks like your infrastructure (webserver, php, ...). First I get, when I google your error is something with Plesk. 1) Are you using Plesk? https://support.plesk.com/hc/en-us/articles/115001626829-PHP-FPM-website-is-not-accessible-on-Plesk-13-Permission-denied-AH02454-FCGI-attempt-to-connect-to-Unix-domain-socket

Cause you are saying, all other stuff on your website is working and it is only the Ranksystem site.. 2) This error happens only on the /webinterface/ or also at the /stats/ site? 3) Are you using a subdomain for the Ranksystem? 4) Could there be different configurations for the Ranksystem on your Apache / PHP against the rest of your website?

[JoniVR]

No, I’m not using Plesk. I already figured out it was the PHP service (see my last comment).

My rank system is just a subfolder in the root directory of the website. No seperate domain.

The problem was the PHP service acting up, which would explain why only the ranksystem wasn’t working because it’s the only part of the site that is using PHP and PHP has been a pain in the ass in general on the server.

It was the first time this happened and I’m wondering if it was just by accident or because I enabled the hashIP feature, but whatever, it’s fixed now.

Thanks for your time and the ranksystem in general, it’s a nice thing to have. I hope this can possibly help @javierlechuXD too.

[Newcomer1989]

It was the first time this happened and I’m wondering if it was just by accident or because I enabled the hashIP feature, but whatever, it’s fixed now.

It shouldn't have to do with this feature. You can try to let it run for a couple of days. If all is working fine, you can try to activate this feature again. When the problem appears with changing this, please contact us again. If not (I am sure it is not), it was a problem with PHP. Perhaps due update, changing configuration or anything else.

Good to know, it is working for you. Its kinda hard to figure a problem out without have a direct access to the system ;-)

[JoniVR]

Just letting you know, it happend once more to me, it happened after restarting the server, so my guess is that the php7.2 service doesn't start autmatically in my case?

Because when I ran:

sudo service php7.2-fpm restart

again it was fixed

My guess is that it's a server specific issue in most cases (probably a php-fpm7.2 config issue), just documenting in case anyone else is running into this for the future.

[Newcomer1989]

I think it is not fixed in your case. You should update your PHP to version 7.3. Inside PHP-FPM with version 7.2 is a bug. Cause the FPM is only for the frontend it doesn't consider the bot, but the stats page and the webinterface.
