No access anymore to the WebGUI | OMV-firstaid - Reconfiguring web control panel failes due to problem with NGINX

Rossum93 · 29. Dezember 2021

Hi all,

In the past I was perfectly able to login to OMV via the WebGUI. It runned on port 81. However, since today I am not able to load the login page from my web-browser. The error message is: ERR_CONNECTION_REFUSED

I've searched and read a lot to fix the problem. Unfortunately without any result, although it seems more people have faced the same problem..

I think most interesting is the log that I get after trying to "Configure web control panel" using the omv-firstaid kit. See part of it below (the attachment contains the full log).

Code

From this log it seems that there is a issue that has to do with nginx.

I've no background in IT. Nevertheless, I learned a lot already after setting up my OMV server a year ago.. However, this problem is to complex for me to solve, so could you please help me. Thanks in advance!

What happened or did you do before the happened?

Rossum93 · 30. Dezember 2021

I've build several Docker images required to set up the Saleor Webshop . Some of these images failed when I tried to create containers of it with the "docker up" command. The docker instructions I followed can be found here: https://docs.saleor.io/docs/3.0/developer/installation

Further, it may be useful to know that I'm running Nextcloud on port 80 (which is still working fine).

macom · 30. Dezember 2021

Is Nextcloud running in docker?

Rossum93 · 30. Dezember 2021

Yes. Although I'm not sure, I think I was still able to access the OMV-webGUI after I set up nextcloud with Docker.

Further, a friend om my also set up Nextcloud the same way as I did and is also still able to access the webGUI..

macom · 30. Dezember 2021

Nextcloud in docker is fine. Run it as well.

Was just wondering because of thie failure

Code

nginx: [emerg] "server" directive is not allowed here in /etc/nginx/nginx.conf:66
nginx: configuration file /etc/nginx/nginx.conf test failed

Did you edit nginx.conf? On my server all lines from line 66 are commented out (therefore not active)

Rossum93 · 30. Dezember 2021

I've looked up my nginx.conf file (see attachment). So, I should also comment out the "server" in this file?

Rossum93 · 30. Dezember 2021

Macom! Thanks for helping me. I've commented out line 67 - 70 (section with title "server") and ran omv-firstaid. I'm able to log in again via the webGUI.

It is remarkable that I've never touched the nginx.conf before. Somehow it was edited by another process..

Thanks a lot!!

macom · 30. Dezember 2021

EDIT: ok you were faster than me

END EDIT

I do not have these lines in my config

Line 64:

Code

client_max_body_size 0;

Line67-69:

Code

server {
client_max_body_size 0;
}

I assume you added them manually. Maybe you wanted to edit nginx.conf in a container and edited the file on the host instead?

Rossum93 · 30. Dezember 2021

You made me doubting and you are right. I've looked it up --> during the setup process of Nextcloud I've been through the following instructions to increase the max upload size to Nextcloud (see link below).

https://dbtechreviews.com/2020…ext%20we%E2%80%99ll%20fix

But I made a mistake. The following section shouldn't be added to the nginx.conf:

Code

server {
client_max_body_size 0;
}

macom · 30. Dezember 2021

Note that you have nginx at least 2 times running.

Once on the host. That is for OMV. Do not edit that. It will have no effect on Nextcloud anyway.

Second in docker. That is where you need to make modifications for Nextcloud.

From the "guide" you linked:

Zitat

You’ll need to edit each of those nginx.conf files. In those files you’ll make sure that you add the following:

This is stupid as you have noticed as it will break OMV. You only should edit the one for Nextcloud.

Rossum93 · 30. Dezember 2021

Yes, you are right. Thanks for you insights and the quick replies!

ALEXSANPEDRO · 17. Mai 2022

I have that mistake(please help. Install nginx in docker, and automatically change nginx.conf and remove all config. Firstaid didnt help me. Can anyone give me standart config which works in omv6!

Im so nonconcentrating when changed config in host, not in docker(
