In the first instance, it's probably good if you could show us a real example. Are you sure it's the plugin for YOUR version of Moodle (even if the version number is higher)?

None of that stuff about asking for the password and so on is coming from Moodle.

Thanks for the comprehensive description

We need to get debugging working. Please make sure debugging is turned right up to Developer and you tick the box underneath to 'Display debug messages'. That *should* produce a full trace along with the error.

 

You might also consider that you are running quite an old version of 4.1. You may want to consider updating to, at least, the latest 4.1.20 to get all the latest fixes. 

I should add... there's an official Docker image for development and testing, here https://github.com/moodlehq/moodle-docker. It's not what you want but may give you a start.

There are some other images for Moodle - e.g. the Bitnami Docker images. I mention them only to caution you against using them. If you do, it would be very difficult to provide support here. We have no idea how they configure Moodle (and nor will you).
