Seems I’m not the only one with this problem, and I can see there’s several threads reporting this issue: - [Upgrade to Ghost v4, but a lot of 503 error](https://forum.ghost.org/t/upgrade-to-ghost-v4-but-a-lot-of-503-error/20762) (this one) - [502 errors after upgrading to Ghost 4](https://forum.ghost.org/t/502-errors-after-upgrading-to-ghost-4/20797) - [Ghost won't start after upgrading to v4.0.1](https://forum.ghost.org/t/ghost-wont-start-after-upgrading-to-v4-0-1/20798) Please let me know if it’s best I started a new thread, or contributed here, which I’ll do for now. I self-host and upgraded using `ghost update` from version 3.42.2 to 4.0.1. I switched to the Caspar theme before doing so as a result of the warning I saw on attempting to upgrade. Other useful versions: - Node: v14.16.0 (also tried with v12.16.2) - Npm: 7.6.3 - OS: Debian 9.13 - MySQL: Ver 15.1 Distrib 10.2.30-MariaDB, for debian-linux-gnu (x86\_64) using readline 5.2 I don’t believe the issue relates to the versions above because running `ghost run` allows the blog to start correctly (that’s the state I’ve left it in for now). At the moment I’m completely stumped and don’t know what to try next. `ghost log` tells me: ```auto [2021-03-17 08:07:24] INFO Ghost is running in production...

An excerpt from my `migrations` table shows: ```auto +-----+------------------------------------------------------------------+---------+----------------+ | id | name | version | currentVersion | +-----+------------------------------------------------------------------+---------+----------------+ | 153 | 01-add-firstpromoter-settings.js | 3.41 | 3.41 | | 154 | 01-update-mobiledoc.js | 4.0 | 4.0 | | 155 | 02-add-status-column-to-members.js | 4.0 | 4.0 | | 156 | 03-populate-status-column-for-members.js | 4.0 | 4.0 | | 157 | 04-drop-apps-related-tables.js | 4.0 | 4.0 | | 158 | 05-add-members-subscribe-events-table.js | 4.0 | 4.0 | | 159 | 06-populate-members-subscribe-events-table.js | 4.0 | 4.0 | | 160 | 07-alter-unique-constraint-for-posts-slug.js | 4.0 | 4.0 | | 161 | 08-add-members-login-events-table.js | 4.0 | 4.0 | | 162 | 09-add-members-email-change-events-table.js | 4.0 | 4.0 | | 163 | 10-add-members-status-events-table.js | 4.0 | 4.0 | | 164 | 11-add-members-paid-subscription-events-table.js | 4.0 | 4.0 | | 165 | 12-delete-apps-related-settings-keys.js | 4.0 | 4.0 | | 166 | 13-add-members-payment-events-table.js | 4.0 | 4.0 | | 167 | 14-remove-orphaned-stripe-records.js | 4.0 | 4.0 | | 168 | 15-add-frontmatter-column-to-meta.js | 4.0 | 4.0 | | 169 | 16-refactor-slack-setting.js | 4.0 | 4.0 | | 170 | 17-populate-members-status-events-table.js | 4.0 | 4.0 | | 171 | 18-transform-urls-absolute-to-transform-ready.js | 4.0 | 4.0 | | 172 | 19-remove-labs-members-setting.js | 4.0 | 4.0 | | 173 | 20-refactor-unsplash-setting.js | 4.0 | 4.0 | | 174 | 21-sanitize-email-batches-provider-id.js | 4.0 | 4.0 | | 175 | 22-solve-orphaned-webhooks.js | 4.0 | 4.0 | | 176 | 23-regenerate-posts-html.js | 4.0 | 4.0 | | 177 | 24-add-missing-email-permissions.js | 4.0 | 4.0 | | 178 | 25-populate-members-paid-subscription-events-table.js | 4.0 | 4.0 | | 179 | 26-add-cascade-on-delete.js | 4.0 | 4.0 | | 180 | 27-add-primary-key-brute-migrations-lock.js | 4.0 | 4.0 | | 181 | 28-add-webhook-intergrations-foreign-key.js | 4.0 | 4.0 | | 182 | 29-fix-foreign-key-for-members-stripe-customers-subscriptions.js | 4.0 | 4.0 | | 183 | 30-set-default-accent-color.js | 4.0 | 4.0 | +-----+------------------------------------------------------------------+---------+----------------+ ``` Which at a quick glance appears consistent with the one pasted earlier. Any advice would be greatly appreciated. --- _[View the full topic](https://forum.ghost.org/t/upgrade-to-ghost-v4-but-a-lot-of-503-error/20762)._
