Describe the bug I get this error several times:

host: megw ingest_date: 202408081738 application: session levelname: ERROR process: main message 192.168.1.21 POST https /screenshot?width=1000&height=1000 404 NOT FOUND - b'Screenshot not found.'

It seems to me this is one cause why crowdsec is banning my external IP. System Description Provide the output of

To Reproduce Steps to reproduce the behavior (for non-installation issues):

  1. Go to Workspace
  2. Click on refresh page because traefik does not always automatically redirect?
  3. See error

Expected behavior A clear and concise description of what you expected to happen. No error logs in debug

Browser If this is a problem with the KasmVNC client, provide details about the browser you are accessing KasmVNC from.

Additional context Add any other context about the problem here.

I also get these errors:

Thank you!

Getting 404 errors for the screenshot API is fairly normal in the full Workspaces. Its due to race conditions, like a user going to their dashboard just when a session is deleted for any reason.

The other two errors you posted are not related.

The SQL error about an UPDATE statement on the kasms table is a known issue that are tracking, however, there are no known negative consequences from that issue.

I don't have enough context around the last error message to provide any response.

But none of these errors have anything to do with your public IP address getting banned on websites or services.
