Only connecting to host servers

hey aternos people
In the past few weeks I was inly able to connect to my aternos server using these host servers. It works fine it's just really annoying copying this link everytime. My other friends don't have this issue. Is this a issue that I can somehow fix?

The problem is just that i can't connect to my server through the normal ip of the server. I'm only able to join the server by using host adresses like derkanabaer.aternos.host:12435 (random example()
