File cannot upload

Hi,
When I try to update media from Search & Register, it shows me

‘Succeeded to the registration of 1 files.’

But also shows

‘File name:/home/nas1r1/29/21/8202129/web/wp-content/uploads/2017/04/EBOOK TEST TEST.jpg
Directory name:/home/nas1r1/29/21/8202129/web/wp-content/uploads/2017/04/
You need to make this directory writable before you can register this file. See the Codex for more information.
Or, filename or directoryname must be changed of illegal. Please change Character Encodings for Server of Settings.’

I check media library. Images still not there.
Is there a way to fix the problem?

Regards,
