Sorry, activity list was not loaded correctly.

Version: OroCRM 3.0 CE, selfhosted
Browser: Chrome (OSX), Safari (OSX)
Problem:

When I open a specific contact I see the flash message "Sorry, activity list was not loaded correctly." on the very top of the page. The console shows this error:

Hi @Konafets,
Please share the log file (var/logs/prod.log), if this is prod environment.
If you are using dev environment, you also could check ajax tab in a developer toolbar for few last requests. Looks like it's returned some exception instead of json content.

Hi @anyt,

this is the repeating error in the log:

[2019-01-28 15:13:30] request.ERROR: Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\BadRequestHttpException: "The request has both a trusted "FORWARDED" header and a trusted "X_FORWARDED_PORT" header, conflicting with each other.

Where can I configure OroCrm or Symfony to distrust one header as mentioned in the error?

[Konafets]

Hi @anyt,

I talked with my hoster. They say that the server setup is not responsible for the headers at all and suggested to configure it in the app.

A curl call shows this (I substituted my domain with example.com):

curl -I "http://crm.example.com/"

Do you have any ideas?
