I have no idea what’s going on. my server once run fedora, and its hostname was fedoraserver. I recently installed AlmaLinux, and now its hostname is tserver. today I was looking at the logs of jellyfin and… Slow HTTP Response from http://fedoraserver:8096

That’s why you should set a (12h-24h tops) lease time on your DHCP…

possiblylinux127 ,

Its your router. (your router doesn’t know you changed hostnames. All it sees is your Mac)

Frederic ,

Reboot your router/DHCP server

lemmyvore ,

And you may want to use shorter DHCP leases in the future.

DHCP?

Your old host registered an fqdn and did mnt remove it, then the new host registered the same ip to a different fqdn.

It happens

I have no idea what you are using for dhcp/dns but start by looking there

Dns caching

db2 ,

Caching.

tubbadu OP ,

Can I clear that cache? It scares me

db2 ,

Probably. What does your dns and/or dhcp?

possiblylinux127 ,

Try rebooting your router

isVeryLoud ,

Sooo basically a ghost :P

db2 ,

In the machine, yes.
