Issue/Introduction

Sometimes when trying to access the Aria Automation UI though a browser the page never loads. You may see some of the following error messages:

        This probably means the server terminated abnormally
        before or while processing the request.

Environment

Aria Automation Config all versions

Cause

One cause of this behavior can be that the network is down or the Postgres database or Redis is not accessible. 

Resolution

  • Check to see if the Postgres service is running and healthy
    • systemctl status postgres-13.service (service name may be different)
  • Check to see if the Redis service is running and healthy
    • systemctl status redis
  • Check to see if you can reach Redis and Postgres servers from the Aria Automation Config server
    • curl https://<ip adress of Postgres server>
    • curl https://<ip address of Redis server>
