Hi OpenEdx Team,

I trust you are all well. I am having the following error when accessing discussion forums in the courses. While trying to debug, I noticed the following errors with regards to the same:

What could be the reason for this error. When I run sudo /edx/bin/supervisorctl status, the following is the response:

The forums service seems to be restarting several times also. Kindly assist in resolving the above.

Is this a new install? If, yes, did you by chance install Open JDK manually before installing Open edX?

Other things that comes to my mind,

1. # Forum service port

/edx/app/forum/forum_env

should have

export LISTEN_PORT="4567"

2. API_KEY in /edx/app/forum/cs_comments_service/config/application.yml and Elasticsearch port:

# Note: the api_key below needs to match the value you have for EDX_API_KEY in lms.auth.json

api_key: <%= ENV['API_KEY'] || 'PUT_YOUR_API_KEY_HERE' %>
elasticsearch_server: <%= ENV['SEARCH_SERVER'] || 'http://localhost:9200' %>

Are you using Comments Service and Notifier app as well?

Open JDK wasn't installed manually, the installation was done correctly.

No.1 is okay. The port is well configured.

My lms.auth.json has the default value: "EDX_API_KEY": "PUT_YOUR_API_KEY_HERE"

The installation hasn't been modified thus unsure about Comments Service and Notifier app, are they enabled by default?

2.a Please check the file

/edx/app/forum/cs_comments_service/config/application.yml

it should have the same API key

api_key: <%= ENV['API_KEY'] || 'PUT_YOUR_API_KEY_HERE' %>

also check the Eleasticsearch port:

elasticsearch_server: <%= ENV['SEARCH_SERVER'] || 'http://localhost:9200' %>

3. Since it's a new install, Notifier won't be configured (it is still running, though) but Comment Service. Leaving Notifier in peace, please check in your lms.env.json and cms.env.json

"COMMENTS_SERVICE_URL": "http://localhost:18080"

If you have instead have FQDN of your server, then you need to open/forward this port.
