Wrong openHAB Log Viewer url

I’ve just updated my Openhab installation from 2.x to 3.0.1. Had some problems with making it work, however after reinstallation of Java it started to operate normally. At least this is how it looks for now.

What I’m struggling with however is accessing frontail through web gui.

This is url opehHAB Log Viewer is pointing to:

And this is what I have configured

It looks that frontail url is right now sum of my local and docker address. When I change it manually to it naturally works.

How can I fix this?
