+Login loop without any clue in access.log, error.log, nor nextcloud.log
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

+If you after fresh installation (Centos 7 with nginx) have problem with first login, you should as first check these files:
+
+.. code-block:: bash
+
+    tail /var/www/nextcloud/data/nextcloud.log
+    tail /var/log/nginx/access.log 
+    tail /var/log/nginx/error.log
+    
+If you just see some correct requests in access log, but no login happens, you check access rights for php session and wsdlcache directory. Try to check permissions and execute change if needed:
+
+.. code-block:: bash
+
+    chown nginx:nginx /var/lib/php/session/
+    chown root:nginx /var/lib/php/wsdlcache/
+    chown root:nginx /var/lib/php/opcache/
