Nothing works after reboot of controller node - internal server error 500

So this error seems to be constantly occurring in different places in my openstack implementation.

But specifically, do I need to do something to restart services on reboot of my controller node? If I reboot it I cannot get any openstack command to run and get this error:

Discovering versions from the identity service failed when creating the password plugin. Attempting to determine version from URL. Internal Server Error (HTTP 500)

This person seems to have had a similar issue: https://ask.openstack.org/en/question/85577/discovering-versions-from-the-identity-service-failed-when-creating-the-password-plugin/ (https://ask.openstack.org/en/question...)

But again this seems to refer to a local_settings.py file that as far as I can tell is part of the horizon/dashboard configuration which I have not got to yet as I only have identity and image services running so far.

I have tried restarting apache2 and checked that keystone is running but didnt help.

Thanks for any advice

Check the following:

# rabbitmqctl list_users

This command should show openstack as one of the user.

It returns this:

Listing users ... guest [administrator] openstack []

I get the same output after a reboot when nothing is working also.

RabbitMQ seems working. Check what all services on controller are up and running [1/3]:

systemctl status chronyd.service
systemctl status mariadb.service
systemctl status rabbitmq-server.service
systemctl status httpd.service 
systemctl status memcached.service

I think I have fixed the problem, still holding my breath as I already had a random internal server error earlier today but everything has been working since.

Due to me being an idiot when I disabled the temporary authentication token mechanism I deleted an extra character after admin_token_auth in the [pipeline:public_api] section of keystone-paste.ini file.

Gonna blame it on the terrible internet here in Hawaii and the lag over my VPN into my home network in New Zealand, the delay in the CLI input meant I deleted more than I meant to...haha.

I really hope this is the issue as everything has worked so far other than that one random internal server error.

Thanks for helping me though, it is appreciated!
