After upgrading from Ubuntu 16.04.5 to 18.04.1, logging into Nextcloud 13.0.5 is very slow

After upgrading from Ubuntu 16.04.5 to 18.04.1, logging into Nextcloud 13.0.5 is very slow. PHP versions on the server 7.0, 7.1 and 7.2.
The Nextcloud, unfortunately, I have only run on the version 7.0, otherwise the PHP module curl is missing.
ipv6 is disabled on router and server. Can it be that the various versions of PHP mess up the apache2?
The login itself to the server takes a little more than 30 seconds, the clients strike on notebook and phone.

I hope for helpful tips. Many Thanks

This helped me, see link:

After deleting the IP you end the editing mode with

quit;

sudo systemctl restart apache2
