Nextcloud Server Stuck Rendomly

ℹ️ Support

Nextcloud version 21.0.1`
Operating system Ubuntu 20.04.1
Apache version 2.4.41
PHP version 7.4.3
Host Server-Windows 2019 Hyper-V

I’m facing a randomly stucking server, It took few minutes to get the login page even from the internal network. and sometimes I gate the login page, and then it works very very slow, and sometimes its stays on the same login page. anyway, the only thing that solves this problem is by doing reboot the server.

Hi @itzikd

More interesting in this context would actually be your Apache config. But I can’t exclude that several different problems are interfering here.

Regarding this error message…

…add a second line in the /etc/hosts file below the existing one with the following content:

127.0.1.1       cloud.yourdomain.com      cloud

Make sure it is the same name, wich is used in the ServerName Directive of your Apache configuration file. If you use a seperate VirtualHost.conf file for your Nextcloud, try to disable the 000-default.conf if you have not already done so… Reboot your server/VM after you did the changes.

#3

Hi,
Thanks for your quick response.
I add this line to the hosts’ file and reboot the server.
I don’t see now any error on the Apache log.
do you think I should do some other setting or just wait a few days to see if it’s happened again?

#4

Yes I would wait and see if it happens again. Maybe you could check the apache error log from time to time and see whether error messages appears again. But I think chances are good that the problem is solved. At first I wasn’t sure about the other error message. But it seems there is nothing to worry about that one, as long as everything works normal… Client denied by server configuration: .ocdata - #3 by danse

#5

Great, I will keep following and update in the coming days.
Thanks
