Passbolt application installation using docker
Here is overview of the setup
I have two prod servers and one dr server running passbolt application as docker containers.
Two prod servers are active-active managed by haproxy loadbalancer server.
DR server is a single server and acts as a replication server, and will be in read only all the time will be used only when prod is completely down.
I have enabled data replication between prod servers and dr server which is working as expected.
Even though data is same across prod and dr servers, our current design has two urls

prod url-https://passbolt.com
DR url-https://passboltdr.com

gpg keys and fingerprint are all same across prod and dr servers
when accessing passbolt application of DR url facing login issues(attached screenshot)

Prod url has no issues with login
want to understand whether as per the current setup since the data is same across prod and dr servers, do i need to use passbolt app url for both environments…

Access to this service requires an invitation.

The same email which i tried login to prod url works fine..
Please suggest on this issue.

This is an internal ngnix conf file issue, we were restricting DR server to perform any db writes and act as read-only using a ngnix conf file, after updating the ngnix conf file on DR server we are able to access the DR url.

Thanks,
