Sabre\DAV\Exception\BadRequest raspberry pi 4B

Greetings,
I have an issue with uploading files!
I found many links to similar issue; but I still have the issue.
I have upgraded from RPi3b+ to 4B
sudenly I noticed that the logs mentioned I was missing the temp folder with following error:

Temporary directory /var/www/nextcloud/data/tmp is not present or writable

this post helped me fixing the issue:
https://github.com/nextcloud/nextcloudpi/issues/617
I actually created the folder, and I modify the config.php and added the temp folder to it (for future upgrade and not get broken again):
‘tempdirectory’ => ‘/var/www/nextcloud/tmp/’
This eliminated the log error for a new ones:

fatal error webdav:
Sabre\DAV\Exception\BadRequest: Expected filesize of 384670 bytes but read (from Nextcloud client) and wrote (to Nextcloud storage) 8192 bytes. Could either be a network problem on the sending side or a problem writing to the storage on the server side

php error:
fread(): Unable to create temporary file, Check permissions in temporary files directory. at /var/www/nextcloud/3rdparty/icewind/streams/src/Wrapper.php#91

php error:
fread(): file created in the system’s temporary directory at /var/www/nextcloud/3rdparty/icewind/streams/src/Wrapper.php#91

Problem solved!
man I had to search for that issue…
So, here are the posts that lead me to solution…
https://github.com/nextcloud/nextcloudpi/issues/617
From here, after researching, I got to the following final solution:
https://help.nextcloud.com/t/cannot-upload-files-error-expected-filesize-5160954-got-8192-appears/59785/10
And now all works perfect (so far so good).
Even the app store that was blanked out, it came back!
I hope this post will save many serches to those with same issue.
