Issue with OctoPrint and PSU Control - Endless waiting for printer connect

[Ic33s]

Hi,
I've an issue starting a print directly from Cura when using PSU Control Plugin:

1. Printer is offline (PSU is off)
2. Cura can connect to the Octoprint server.
3. I press "Print with OctoPrint" and the PSU goes on, in the web ui of octoprint I can see, that after 15 seconds octoprints connects to the now running/online printer.
4. But: Cura stays waiting for octoprint to connect to the printer. The connection window in Cura says: "Waiting for OctoPrint to connect to the printer..."
5. After some minutes ... I than tried to "Queue" the print job with the result, that the gcode is uploaded to octoprint and selected for printing in the web ui. => Communication Cura<->Octoprint and Octoprint<->Printer is working at that time, but Cura is still waiting on the Printer connection.

Used software versions:

• Windows 10 64bit
• Cura => V5.1.0
• Cura Plugin: OctoPrint Connection => V3.7.2
• OctoPrint => V1.8.2
• Octoprint Plugin: PSU Control => V1.0.6
• Octoprint Plugin: PSU Control - Tasmota => V1.0.1

Would be great, if you can help me and thank you for your great Cura plugins.
