Redmine. Puma::HttpParserError: Invalid HTTP format, parsing fails

Question

I encountered this problem in Redmine 5.1.1 Redmine 5.1.1 (docker)

Environment:
  Redmine version                5.1.1.stable
  Ruby version                   3.2.3-p157 (2024-01-18) [x86_64-linux]

  Environment                    production
  Database adapter               Mysql2
  Mailer queue                   ActiveJob::QueueAdapters::AsyncAdapter

I have a php script (PHP 8.2, via Redmine RestAPI) that closes tasks in Redmine based on a certain status and tracker. After updating Redmine to v. 5.1.1 (old. v. 4.1.5) when I run this script I get an error:

2024-02-27T08:13:14.382534085Z 2024-02-27 10:13:14 +0200 HTTP parse error, malformed request ("GET /issues.json" - (-)): #<Puma::HttpParserError: Invalid HTTP format, parsing fails. Are you trying to open an SSL connection to a non-SSL Puma?>

I'm using nginx reverse proxy on another server to use Redmine over https. The previous version of Redmine 4.1.5 (without Puma) worked perfectly when running my on php script. Tell me what I should fix in the configuration to eliminate this error. Thank you in advance.

changed the php script configuration from https to http.

There was recently a change in the issues API endpoint to make it more consistent, if you are expecting stuff like "status=" (without any value) it might be broken. See the related ticket here

To start you should try with 5.1.2 where they improved the behavior of this endpoint so you can check if the issue is on puma side.
