-
Reverse proxy and version _(e.g. nginx 1.27.2)
- PHP version (e.g, 8.3):
- 8.1.32
- Is this the first time you’ve seen this error? (Yes / No):
- yes
- When did this problem seem to first start?
- After rollback
-

Summary of the issue you are facing:
We had to rollback our Nextcloud to a previous version. We are using AWS S3 for primary storage. In the database, the oc_filecache table has the file information. The files exist in S3. But I cannot pull up the files in Nextcloud. I can search and find files (I’m guessing this is searching oc_filecache), but when I try to preview or download the found file, it doesn’t work. Previewing the file just spins with no result. Attempting to download the file gives a general “500 Internal Server Error”. I tried occ files:scan with no change.
Steps to replicate it (hint: details matter!):

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
