Nextcloud desktop login issue

Please make sure "log_errors" is set to "On" in your PHP configuration, and "error_log" is configured with a writable path. Then check if there are any related entries written in the error log file when trying to connect to FileRun using the desktop app. Would also be useful to check if there are any errors logged in the Apache error log. or in the Nginx log.

Hello! 

My instance is deployed under the control of HestiaCP (analogous to VestaCP). Apache works with nginx proxy.
Here are the nginx server settings common and for a specific domain with SSL and HSTS. IP address and domain name changed to uorIP and ourDomain

Logs for PHP are configured and do not contain errors.
Added entry to custimizables / config.php file.

Also providing Apache log content after trying to connect from Nextcloud mobile app

ourDomain / dav.php takes a username and password and displays an XML document.
The Widows explorer connection also connects and displays content.
All the main functionality of FileRun works.
Installation is performed according to the instructions for UBUNTU 20.04. PHP 7.4 version on PHP-FPM.
Thanks for any help.

I see that signing in does open the authorization page. What do you see?

Why do you manually configure the hostname inside FileRun's config?

I see a clean white screen. The authorization form (login and password) is not displayed. 

Your question: "Why do you manually configure the hostname inside FileRun's config?" 

This is what you mean? /customizables/config.php file?

I tried it already in the process of finding a solution to the problem. But that didn't make any difference. I also see a blank white screen when I click "Connect WebDAV App" in the profile settings. A page with a URL: https://ourDomain/oauth2/authorize/?response_type=webdav&client_id=Generic0000000000000000000WebDAV&redirect_uri=nc%3A%2F%2F&state=state5df4f4de0f81e&scope=webdav opens and nothing is displayed either

You should not have to set anything in the config file. It can even cause this problem.

I deleted the contents of this file and reloaded Apache. This did not help in any way and the logs are the same.

If you contact us (https://filerun.com/contact) with remote access (FTP or similar) to the FileRun installation folder, I will troubleshoot this for you.

Ok, I will analyze this possibility shortly. Thanks for the support!

Hello! I have sent you data for FTP access to our server (on https://filerun.com/contact).

Thanks! That helped. I think you should add this item to the installation manual (in the contents of the filerun.ini file)
