Thank you. Following your advice we could mitigate the issue. It was a network misconfiguration the IT could fix (bad gateway). Anyway, I still have the warning message being displayed, but the connexion now works (thru fallback I guess). There might be another issue, I will check the other points you enumerated. Thx for your support. Le 19/12/2023 à 18:11, KEREM CELIKER a écrit :
Hey Sadir,
It seems that the error message you have is related to the discovery process of the OpenStack services. Discovery is the process of finding and registering the endpoints of the OpenStack services, such as Keystone, Nova, Glance, etc. This allows the clients to communicate with these services using their service URLs.
The error message indicates that the discovery process failed to contact the endpoint at http://yeti.ds.eurecom.fr:8080/v1/AUTH_da0d8589692741d1b2a82956568227e6 for discovery. This endpoint is supposed to be the base URL for all the OpenStack services on your server. However, it may not be reachable or valid for some reason.
There are a few possible causes and solutions for this error:
The endpoint may be down or unreachable due to network issues. You can try to ping or curl the endpoint from your client machine and see if you get a response. If not, you may need to check your network configuration and firewall settings on both your server and client machines.
The endpoint may be misconfigured or incorrect in your devstack configuration file. You can check if the endpoint is specified correctly in the [nova] section of your devstack configuration file1. For example, it should look something like this: [nova] region_name = RegionOne memcached_servers = localhost:11211 endpoint = http://yeti.ds.eurecom.fr:8080/v1
The endpoint may be incompatible with your OpenStack version or service version. You can check if your OpenStack version and service version are compatible with each other and with the endpoint URL. For example, if you are using Keystone v3, you should use https:// instead of http:// in your endpoint URL2. You can also check if there are any updates or patches available for your OpenStack version or service version that may fix this issue.
The endpoint may be blocked by a proxy or VPN server that you are using. You can try to bypass or disable any proxy or VPN server that you are using and see if that resolves the issue.
I hope these suggestions help you..
