Hello, Maybe increasing the value of a setting like memcache_pool_conn_get_timeout can help? Cheers, Maysa. On Wed, Jun 15, 2022 at 2:05 PM Eugen Block <eblock@nde.ag> wrote:

Hi,

I remember having a similar issue a few years back in an older openstack release, probably Ocata. We had difficulties loading *all* instances in the admin tab in Horizon dashboard. It turned out to be a memcached misconfiguration. I don't recall the details, unfortunately. But I'd start with memcached.

hi Team,

We have Xena release installed on Ubuntu Openstack, Lately we are getting "504 Gateway Timeout error ", As the we moved from 1 node to 3 node Open Stack i do not see any error in haproxy , neither there is a time out when i ping external-VIP-IP configured.

Apache 2 are also loaded, tried to delete the Horizon Container and created it again, but no errors, Still the same errors.

Any guesses on that
