Drupal 8. how to make a logo not on localhost but on 192.168.1.20?

Question

CMS

The problem is this: I replaced the standard Drupal logo with my own, and it disappeared from the rest of the computers, because. the address was issued like this
localhost/themes/bib-bartik/logo.svg
How to fix this, and where to write another path to the file?
The theme was implemented like this: I copied the theme folder to /themes/bibbartik
and then

find '/var/www/drupal/themes/bib-bartik/' -exec sed -is/bartik/bibbartik/ {} \;

probably, the problem is that the site thinks that it is on localhost (in the site information page. where you can select the start page address localhost/node ) but how to make it suddenly decide that it is on 192.168.1.20 without reinstalling site?
