I tried it a few times, I increased the phph memory-size to 512M, but nothing helped.

Please help, if anybody has an idea.
Thanks.

Fishing in the dark is the wrong way to investigate further. You first have to check the Nextcloud log file and also the web servers log file to find related errors which might point to the root cause of the problem. I don’t know how this can be done, because you haven’t really provided valuable information about your environment. Eventually your hoster can assist you getting that information.

Yes you are right, sorry.

The Nextcloud logs I can already provide, the apache logs had been deactivated by the provider and will be reactivated again tomorrow morning.
Maybe from the nextcloud log something can be seen already.

I can not see any error in it, but an excerpt is:
(I have to find out how to provide a file here)

Here the apache log:
