AWS credentials invalid & "server on" error

[Brian Yin]

Hi,

I've started to get the following error message (this is only a recent problem—I'm not sure yet exactly why it started):

Sorry, unable to connect to Amazon Mechanical Turk. AWS credentials invalid.
You can still use the psiturk server by running non-AWS commands such as:
- `psiturk server <subcommand>`
- `psiturk server on`
- `psiturk server off`
- `psiturk debug -p`

and when I run psiturk server on I get:

Traceback (most recent call last):
  File "src/gevent/greenlet.py", line 908, in gevent._gevent_cgreenlet.Greenlet.run
  File "/usr/local/lib/python3.8/dist-packages/gunicorn/arbiter.py", line 242, in handle_chld
    self.reap_workers()

    raise HaltServer(reason, self.WORKER_BOOT_ERROR)

(I don't know if the two problems are related.) My requester and sandbox requester account are each connected to my AWS account and I'm able to successfully run the test code Dave shared here (also, trying a new set of credentials didn't fix anything). I run into these issues both with 3.2.1 and 3.3.1. Any help would be appreciated!

Thanks,

Brian
