IO Broker OctoPrint adapter loses connection to API

What is the problem?
The adapter in the IO Broker keeps giving me the following error message and does not connect to the API.

A connection is therefore no longer possible.

What did you already try to solve it?

I have already switched off or uninstalled several plug-ins.
However, all of this has had no effect.

I have already opened an issue for the OctoPrint adapter, where you can also find the more detailed logs from the IO Broker:
Git Hub Issues => Meldung "timeout of 2000ms exceeded" #70

The API connection to Heimdall works, apparently without problems.

Logs
Here is the log from my OctoPi:
octoprint (2).log (152.6 KB)

You can find the log of the IO Broker in the GitHub Issues.

Additional information about your network
I use a Unify network (switches, Acesspoint).
I use a Fritz Box 7490 as a router.
OctoPrint runs on a Pi 3 B+ which is powered by a PoE HAT.

IO Broker runs on an Intel NUC in a Proxmox VM.

The problem was solved by a patch.

Thank you @klein0r
