Hello

I installed odoo using network on debian machine and it works correctly. Then I changed network to LAN (offline) and on different PC after login form I receive:

Error:

SyntaxError: Unexpected token < in JSON at position 18 at fetch.then.res (http://10.10.10.15:8069/web:21:142) at <anonymous>

Server is the same.

Also on some machines using chrome and edge I can reach odoo in browser. 

Small version: Installation using manual -> creating db and users -> connecting. Using internet - ok, but connecting using LAN -> not working.
