Grafana OPCUA Plugin failed to start

I'm new to both portainer and grafana and I'm attempting to get an OPC UA connection up and running.

Grafana is running on a container on portainer. I have access to the front end/console etc.

When running "grafana-server restart" there are a few errors, some about port 3000 "address already in use". But what's important here, the opcua plugin fails to start with error:

Unrecognized remote plugin message: \n\nThis usually means that the plugin is either invalid or simply\nneeds to be recompiled to support the latest protocol.

I've installed using the basic "grafana-cli plugins install grafana-opcua-datasource" command. the OPCUA plugin is an option on the front end, however, testing it simply gives me a "plugin unavailable" popup. I have upgraded Grafana and updated the plugin. The Grafana version is high enough to work with the plugin (according to https://grafana.com/grafana/plugins/grafana-opcua-datasource/?tab=installation)

Anyone have any ideas of where I can at least look for problems?

I've run into the same or similar problem:

It's a .net aplication right? i tried it in a dockerized enviroment on a debian host. logger=settings version=8.4.7 commit=23bf3ef043 branch=HEAD compiled=2022-04-19T16:05:49+0000

i also tried to add the .net enviroment:

FROM grafana/grafana:latest

USER root

RUN apk add bash icu-libs krb5-libs libgcc libintl libssl1.1 libstdc++ zlib wget
RUN apk add libgdiplus --repository https://dl-3.alpinelinux.org/alpine/edge/testing/

RUN mkdir -p /usr/share/dotnet \
    && ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet 

RUN wget https://dot.net/v1/dotnet-install.sh
RUN chmod +x dotnet-install.sh
RUN ./dotnet-install.sh -c 3.1 --install-dir /usr/share/dotnet
RUN ./dotnet-install.sh -c 5.0 --install-dir /usr/share/dotnet
RUN ./dotnet-install.sh -c 6.0 --install-dir /usr/share/dotnet

RUN grafana-cli plugins install grafana-opcua-datasource

but with the same result.
