503 Service Unavailable


I just did this (How to remove port 8090 from CyberPanel - #2 by lmilani - Blog Posts - CyberPanel Community) a few hours ago and right now my website is saying this

Service Unavailable
The server is temporarily busy, try again later!

I have been trying to install a software and after the installation I get the same error?

any idea? Thanks

Port 8090 is giving you 503 error?

You can try systemctl start gunicorn.socket

No, I can log in using IP:8090 but the new website to use the panel without the port and another website is giving me that error 503

Used that command and it still doesnt work.

503 error means you did not setup proxy app correctly. What is output of

cat /usr/local/lsws/log/error.log | grep ERROR

[root@host ~]# cat /usr/local/lsws/logs/error.log | grep ERROR
2019-02-11 00:03:19.967116 [ERROR] [config:server:vhosts:vhost:Example:context:/protected/] Path for context location is invalid: /usr/local/lsws/Example/html/protected/

but its not just the web panel its another website too that is not running in a port.

is there a way to install the 1.7 version? bc the another website was working before the update

*Just wanna test

I am not sure what you are trying to say. Your website should run without specifying any port as browser default is 80 and 443.

In recent updates OpenLiteSpeed is not upgraded, so you use the same OpenLiteSpeed even after the upgrade. So it does not matter if you have version 1.7 of CyberPanel.

However, if you want you can upgrade OpenLiteSpeed

yum update
yum upgrade openlitespeed

Still not sure if you have a problem with CyberPanel or the websites being run, please explain the steps to reproduce the issue.

I followed this guide and it worked for a few hours I could access to the panel without the port but after that the website just gives me 503 error…

If I remove the Rewriterule the website works as default website but if I add the rewrite rule again it keeps giving me the 503 error…

I also get 503 error in another website, happened the same the website worked a few hours and after that just 503 is shown.

is there a way to check each website logs? to get the cause of the error?

(the website home logs just show this)

[12/Feb/2019:02:48:35 -0500] “GET / HTTP/1.1” 503 665"

We can talk about your other website first. Please do not mix 2 issues. Do you have enough resources available on your server?

And your rewrite rules on the other site does not have anything to do with 503 error on other sites.

You can also turn on php error logs. Also, look for error log files in


Well, I just use a VPS with 1G RAM - 1 Core - 20GB… Just for personal sites… *I dont think thats the problem the first time I added the website it worked for a few hours like the site for panel access after that I just get 503…

Turned on PHP errors readded the website and this is what I got from the error.log in /usr/local/lsws/logs/

Me too, I have the same problem as you and I couldn’t find any solutions.

I had a similar issue but it turned out to be the lscache plugin, it didn’t like a specific setting

source /usr/local/CyberCP/bin/activate
pip install --ignore-installed -r /usr/local/CyberCP/requirments.txt
virtualenv --system-site-packages /usr/local/CyberCP
systemctl restart gunicorn.socket

This one has solved my problem.

have been having this issue for at least 6 months now. am about to switch back to wordops because I’m tired of logging into ssh and rebooting the server to fix the 503 error (happens on multiple sites on the same server).

i have 4gb of ram, 2 cpus on my vps. plenty of resources for my websites (htop shows little resource usage during normal use).

then randomly I see 503 errors when checking the backend or frontend of my wordpress websites

it’s started to negatively impact my google search rankings because google is sending people to a 503 errors.

how has this gone for so long without a fix?

Same here, please help!!

This solution worked for me

source /usr/local/CyberCP/bin/activate
pip install --ignore-installed -r /usr/local/CyberCP/requirments.txt
virtualenv --system-site-packages /usr/local/CyberCP
systemctl restart gunicorn.socket


I just installed cyber panel 8090 server panel gives error 503 I am using linuxrocky commands give error systemctl start gunicorn.socket

when you trying to change your admin without port 8090 be sure your 443 and 8090 is accessible from outside world

I assumed you are install cyberpanel in your office machine which is intranet enviroment

I had change my external app address from “panel.mydomaind.com:8090” to “”
extprocessor cyberpanel {

  type                    proxy
  maxConns                100
  pcKeepAliveTimeout      60
  initTimeout             60
  retryTimeout            0
  respBuffer              0
