Frontend available if upgrading to the 102/103

Tearing my hair out. After upgrading to 102 or 103 my frontend is no longer available.
Error log clean. Downgrading to 101.3 solves the issue

Simply states cannot connect
Looking at netstat – listen it’s not opening the port
Am i missing some breaking changes?!

Although it seems to open a port at
local.address.local:51827

frontend:
  themes: !include ./themes/themes.yaml
  javascript_version: latest

lovelace:
  mode: yaml

default_config:

map:
config:

http:
  ip_ban_enabled: False
  login_attempts_threshold: 5
  base_url: https://www.xxx.ru:8123
  ssl_certificate: /etc/letsencrypt/live/www.xxx.ru/fullchain.pem
  ssl_key: /etc/letsencrypt/live/www.xxx.ru/privkey.pem

You may not think the log is relevant, bit it may be.

Well the error log was clean as it could be. Scrolling through the pages of debug - also 0 results.

Strangely enough - downgraded to 101.3 Solved.
Upgrade to 102.3 - failed
Downgrade 101.3 FAILED
Upgrade to 102.3 SOLVED!

Seems like some dependency bug.
