Hendrik;
Since the hostname / FQDN for use by Ceph for you RGW server(s) changed, did you adjust
the rgw-api-host setting for the dashboard?
The command would be:
ceph dashboard set-rgw-api-host <fqdn>
Thank you,

Subject: [ceph-users] Object Gateway not working within the dashboard anymore after
network change
Hi all,
we are currently experiencing a problem with the Obejct Gateway part of the dashboard not
working anymore:
We had a working setup were the RGW servers only had 1 network interface with an IP
address that was reachable by the monitor servers and the dashboard was working as
expected.
After our initial tests everything was working great and we decided to add another
physical link to the RGW Servers for the traffic to the clients.
With that network change we also had to set the default gateway to the new interface while
adding static routes for the rest of the ceph environment.
To avoid issues with hostnames (the old hostname now resolves to the new interface) we
added another hostname for the internal traffic, purged the gateways from ceph and added
them again via ceph-deploy rgw create with the new hostname.
The S3 communication is working perfectly fine as it did before, we can reach all buckets
and the monitors can communicate with the Gateway. The Dashboard however throws the
following error whenever we navigate to any of the object gateway menus:

We are running ceph version 14.2.9 on CentOS 7.7. Any help on how to debug this would be
greatly apreciated.
