Update:

If i create a new empty databse it sync (2kB)

If i try it with my Standard, it wont work (7,2MB)

[Gronkdalonka]

Same here but with seafile as webdav backend. Other webdav clients are able to sync the keepass db just fine and it works if the db file is fresh and has not too many entries.
My default db is just ~ 700 kB in size and from the logs i could only gather that the
request results in a 502 error because the upstream wsgidav server behind an apache2 reverse proxy notices a sudden end of the data stream.

Ok, after trying something this weekend, I get the following solution:
With nextcloud-aio it won't work,
but with a simple nextcloud it works... It seems to be an issue in nextcloud.. so done for me...
