Hi @neyusyt,
Can you confirm exactly how you installed BookStack, and if there are any other parts in play (Proxies/Cloudflare/Other HTTP Layers).

@neyusyt We have no official start.sh on our homepage?

Either way, it's not clear where the error is coming from.
Assuming you've used our Ubuntu 22.04 install script, can you watch the /var/log/apache2/access.log file and confirm if you see lines added exactly when the error occurs.
If not, it's likely something in front of the BookStack machine webserver blocking the request. It's worth checking logs for the Cloudflare proxy if they provide it.

I can't open that file: /var/log/apache2/access.log, because this location doesn't exist. I can't the logs from Cloudflare Proxie. I searched a lot, but i cant find a log file.

How exactly did you install BookStack? You may need to look into these folders with superuser/root privileges.

@ssddanbrown I installed with this script:

Download the script
wget https://raw.githubusercontent.com/BookStackApp/devops/main/scripts/installation-ubuntu-22.04.sh

Make it executable
chmod a+x installation-ubuntu-22.04.sh

Run the script with admin permissions
sudo ./installation-ubuntu-22.04.sh

edit .env file
nano /var/www/bookstack/.env

in the log file (/var/log/apache2/access.log) isn't anything suspects.

But do you see any lines logged at exactly the same time you reproduce the error?

@neyusyt Okay, that often means that it's an issue before the request is hitting the webserver.
Could be an issue around that cloudflare proxy.

Other things to try:

If possible, try without having the cloudflare proxy involved to rule that out.
Try a much smaller file image file size to see if that works.
Look at the request and response in the network tab of the browser developer tools to see if there's more information provided there (Request would likely show as a red line within the table, after reproducing the error).

Since there's been no further follow up I'll close this off.

@ssddanbrown hello Dan. I was having the same problem.

I was able to fix the issue by deactivating Cloudflare proxy. I still want to use Cloudflare for 2 reasons:

SSL certificate (the Bookstack installation guide does not provide information about installing SSL)
Cloudflare gives many features for my website for free and it is a common practice to use it.

What can I do to enable Cloudflare? Thanks!
