The current version of phpMyAdmin used in lando is 5.1.1, released on 2021-06-04.

You seem to be using one of the docker containers, and phpMyAdmin rarely introduces breaking changes. It should be trivial to update it.

Is there a reason this is stuck on a version from nearly three years ago?

Hello,

1. Created Drupal 9 multisite with 2 subsites successfully
2. Created a separate database for each site
3. Logged in to PHPMyadmin databases for 2 subsites are not displayed there. Databases are present in MariaDB.
4. However database for the main site is present as it is.

Lando version : v3.1.4
Here is .lando.yml

name: healsecurity_lando
recipe: drupal9
config:
  webroot: web
  php: '7.4'
  composer_version: '2.1.9'
  # via: apache:2.4
  via: nginx
  database: mariadb:10.4
  xdebug: false
services:
  phpmyadmin:
    type: phpmyadmin
    hosts:
      - database
  subsite1:
    type: mariadb:10.4
    portforward: true
    creds:
      user: drupal9
      password: drupal9
      database: subsite1
  subsite2:
    type: mariadb:10.4
    portforward: true
    creds:
      user: drupal9
      password: drupal9
      database: subsite2
proxy:
  appserver_nginx:
    - main.lndo.site
    - subsite1.lndo.site
    - subsite2.lndo.site

Attached is the screenshot of PHPMyadmin

Please let me know if I am missing any configurations.

Thanks
Prashant

I'm new to lando.
I installed phpmyadmin according to the lando manual, then, I could access phpmyadmin via browser.
But after I modified my_custom.cnf in ./lando/config/mysql/, I restarted myApp from Docker Desktop and I restarted land using the command, lando stop and land start, vital info listed the url for new phpmyadmin, and I opened the url by browser then, error displayed like "can't connect to the server(localhost)" and phpmyadmin isn't shown.
