phpmyadmin page load

What is the true essence of the Nine Yin dynasty? 3 months ago (sth. or sb) else 33

With wordpress installed in docker on my home server local.ip:80.
When I visit this address, it loads immediately, the
I have port forwarded the port and when I access external.ip:forwardedport from another network (mobile) it takes about 1 minute to load.
For example, the phpmyadmin page loads immediately from the external web, so I think it might have something to do with some wordpress settings I don't know about?
