What information is logged about this?

Is there an HTTP proxy on that network that is required for accessing the web?

Is config.preferred-install set to "source" in composer.json?

Hi it looks like this issue
https://www.drupal.org/project/drupal/issues/2920285 🐛 Update module can get 'stuck' with 'no releases available' Needs work
if it's the case the drush command will fix it

Hi @cilefen the logs do not provide any type of information and to my knowledge there is no HTTP proxy required.
config.preferred-install is currently set to "dif" in composer.json

  },
    "config": {
        "preferred-install": "dist",
        "sort-packages": false,
        "platform": {
            "php": "8.1.13"
        },

I ran drush php:eval "\Drupal::keyValue('update_fetch_task')->deleteAll();" from #7 and it worked! I can see the available updates again. Thank you ericdsd for the recommendation.

Uninstalling "Update Manager" fixed my problem. None of the other suggestions worked.

I also realized later in testing that the update settings page was throwing errors. If you aren't seeing updates and the settings page is throwing errors, try re-installing the update manager. I could be wrong but I believe it has to do with the email address and how it was stored in past versions.
