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

Hi.
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]
  Rails version                  6.1.7.6
  Environment                    production
  Database adapter               Mysql2
  Mailer queue                   ActiveJob::QueueAdapters::AsyncAdapter
  Mailer delivery                smtp
Redmine settings:
  Redmine theme                  Tw-style (includes JavaScript)
SCM:
  Subversion                     1.14.2
  Mercurial                      6.3.2
  Bazaar                         3.3.2
  Git                            2.39.2
  Filesystem                     
  Gitlab                         4.14.0
Redmine plugins:
  redmine_agile                  1.6.6
  redmine_checklists             3.1.22
  redmine_gitlab_adapter         0.2.0
  redmine_hourglass              1.3.0-dev
  redmine_resources              2.0.0
  redmine_wysiwyg_editor         0.32.0
  redmineup_tags                 2.0.13

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:

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.

Please show your current nginx and puma config.

According to the puma configuration, I don’t know where you can look it up.
I updated redmine via the official docker image, in the Gemfile, the installation was specified as 'gem puma'.
In the log I see this:
