Hi Seyfettin_Gundogdu,
your recent changesets have left behind several errors in the OSM database regarding not connected ways (red dots):

https://tools.geofabrik.de/osmi/?view=routing&lon=34.40835&lat=36.82967&zoom=11&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas%2Cunconnected_open_ends_1

As you may know these ways cannot be used by routing software.
Can you please fix this?
Kind regards
Guido
