Typo3 (8.731) Plugin Controller ignored the first time, every call after that works fine

I have a typo3 plugin, that handles the /code/xyz.

When a code is called the first time it doesn't work and results in a 404. When it's called the second time it's running into the controller (I've set breakpoints there).

What could be the reason for the difference of behavior between the two calls. With nothing changed by me two calls right after each other exhibit the same behavior.

Thanks in advance.

  • Ok, this one was a hard one to crack.

    Even though we thought is was Realurl the problem was a different one.

    The integrator doing the upgrade from 7 to 8 missed one breaking change:
