Error uploading files after update to

mariadb Ver 15.1 Distrib 10.1.48-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
Debian 10

Docs not installed, upload and save files only.

Screenshot below.

Installation behind reverse proxy.

Works fine without proxy.

Hello @ingvar42

Please elaborate on this: category set as Docs (Document Server) but from the description and the screenshot it seems that you are using Workspace, is that correct?

Did you follow any guide to configure proxy for ONLYOFFICE product?

Yes, it is.

But I can not upload files via Documents also.

Unfortunately, we do not have any official guides on how to run, configure or maintain Workspace portal behind proxy.

Actually it happened before but I do not remember how problem was solved that time.

I think that I need to compare Workspace config files before and after update.

Interesting. I can upload files to Project via Conversations.

As I mentioned previously, we do not have any examples of proxy configuration for Workspace portal. If you manage to solve the issue, please feel free to share your experience with us.
