Graylog 4.0 - Web Interface no longer accepts FQDN
Ubuntu 20 LTS
After updating to Graylog 4.0, we noticed that we are unable to connect to the web interface with the use of our FQDN. We receive the following error;
We must use the IP address to access the web interface. Prior to 4.0, we were able to use both. Configuration hasn’t changed other than the move to 4.0.
How do we allow web interface access to the FQDN?
