400 expected filesize xx got y

Nextcloud version: 11
Operating system and version: CentOS 7
Apache version: 2.4.6
PHP version: 5.6.30

Some different files do not sync. The nextcloud log is:

“app”:“webdav”,“message”:“Exception: {“Message”:“HTTP\/1.1 400 expected filesize 7791737 got 12344”,“Exception”:“Sabre\\DAV\\Exception\\BadRequest”,“Code”:0,“Trace”:”#0

I didn’t find the answer for the forum although there is a similar question.

Can you help me?

Thanks in advanced.
