Varnish for WordPress in a Docker container in Plesk Onyx

[Daniel Slyman]

Does anyone else have the problem that they can't login to WordPress? The website works, HTTPS works, but when accessing /wp-admin/, I get redirect loops

Correction, that seems fixed. However, now I get Mixed Content Warnings when accessing the admin pages. Apparently the WordPress Admin Stylesheets are only loaded via http, not https, any ideas?

Use a plugin such as simple ssl to force https?

Didn't work, I scrapped the project.

Hello,
To avoid issues when WordPress is running behind a reverse-proxy without TLS, you just have to add the following line to your wp-config.php :

$_SERVER['HTTPS'] = 'on';

There is one thing this tutorial doesn't explain.

"Firewall / Plesk Firewall."

This is the reason many of you getting "Error 503 Backend fetch failed" error.

In your Firewall / Plesk Firewall, Open incoming to Port 7080 from any host.
