Error When Adding or Editing Adobe PDF Actions

Hello!
I've been using the Adobe PDF connector without issues until recently, but now I'm unable to add or edit actions. When I try to add an action, I receive the following error message:

"ERR_BAD_RESPONSE. Request failed with status code 500"

Additionally, this month I reached 80% of the 500 monthly transaction limit for the first time.
Could this be related to the issue? Any help or insights would be appreciated!
