Domain Resolving Issue
I am running a Mailman 3 server with about 5 list domains configured on it. Most of them resolve quickly both to Postorius and HyperKitty. However there is one domain that resolves very slowly. Once it does, access to other pages/tasks go quickly. If you don't do anything with that domain in the browser after about 5 minutes, it takes its time again to resolve. What could be causing this? The webserver is Nginx. Not sure if this is a Mailman 3 issue or not.

It is unlikely that this has anything to do with Mailman. The faster access after first time is probably due to local caching of DNS entries.
Try checking your DNS servers for the domains and how long they take to respond. Your browser is probably just waiting more for DNS response. Mailman should be responding with similar lag for all the domains.
