Solved Problem with NGINX when installing/restarting any app

[revck]

Hello,

Initially Cloudron was working fine, then I added volumes to it and applications, and problems arose.
Cloudron is running inside vmware workstation pro, with volumes mounted.
Volumes are accessible by command line, and on Cloudron Web GUI they show as a green circle, but when I click 'open file manager' not all show content, even if I wait. I believe the errors below started presenting after adding volume, but I do not know if it is coincidence or it is linked, so let's hold our thoughts for now.

Adding/Starting/Installing any app now gives me NGINX errors. If I restart Cloudron, it seems for a bit it allows me to install those apps that were failing.
Restarting Cloudron gives NGINX errors, and I have to manually, each time, execute the following:

cat /var/log/nginx/error.log
sudo rm -rf /etc/nginx/applications/config-that-was-failing-on-errorlog.conf
sudo systemctl start nginx

Adding/Starting/Installing apps shows the following:

Task Error
If a configuration, update, restore or backup action resulted in an error, you can retry the task.
An error occurred during the start app operation: Nginx Error: Error reloading nginx: reload exited with code 1 signal null

An App was showing Error : Nginx Error - Error reloading nginx: reload exited with code 1 signal null, and when looking at the logs it initially errored, but then it started, so I manually navigated to the page and it work, despite Cloudron always and still showing it as errored, and not being able to access from the Cloudron Homepage. What can I do?

Here's the error shown in error.log for most apps related to nginx:

It's getting quite annoying, and I hope you can help to fix it, as you can read there are multiple problems, thanks in advance.

@revck If you look into journalctl -u nginx , it will usually mention what line of the config is failing. Can you please check?

[revck]

@girish definitely, I did check it previously and seems no error is found, here's what I get:

/etc/nginx/applications$ journalctl -u nginx
-- Logs begin at Mon 2021-08-16 22:35:16 UTC, end at Wed 2021-08-18 01:44:22 UTC. --
-- No entries --

@revck so from your first post, it looks like you are aware of which config file is failing. Do you see anything suspicious in that one, like some encoding issue or is a special non latin1 domain used for those?

Further, have you added custom nginx configs which may be included and confusing the system?

Finally if you want us to take a direct look at your server, please enable remote support send us a mail with your dashboard domain and reference to this thread to support@cloudron.io

I am currently debugging that instance, but just for others to read up, using nginx -s reload as root usually reveals the syntax errors in config files right away, like it was in this instance as well.
