OctoPrint API Key Error

[KGuthrie040]

Cura Version
5.4.0

Operating System
Windows 11

Printer
Ender 3 Pro with Octoprit

OctoPrint Version
1.92

Every time I try to send a print to OctoPrint I get an API key error.

I have tried to reset my API key as well as redownload the addon. Nothing I have done works. I have another printer with Octoprint 1.9.0 and I do not have the same issue.

Has something changed between 1.9.2 and 1.9.0?

Are you trying to turn on the PSU through OctoPrint with a non-admin account?

If so, you need to make sure the user you have configured in Cura has the PSU Control: Control permission. Settings => Access Control. Either give your user an additional permission, or add it to a group and give the group the permission.

In my case, I set up a user and added it to the Operator group, and gave the PSU Control: Control permission to the Operator group :

If not, check your OctoPi logs (tornado.log) and search for something like this:
