Mediaplayer isnt working after name change

[MrJekyll23]

A few days ago I installed HASS.Agent and tried it out. Everything was working fine.
Then I decided to change the name, reconfigured my sensors and got them working again.
Today I recognised that the mediaplayer was unavailable and it's name was the old one. I deleted the HASS.Agent device in HA. Auto discover detected a new one and I added it. But it unfortunately it has the old name and is unavailable again.

Things I have tried so far:

• deleted device in HA again
• reinstalled HASS.Agent in HASC
• reinstalled HASS.Agent on my PC
• reconfigured everything but no change

Hello, similar problem:

I have a new PC (Windows 11) and cannot connect to the Media Player with HASS.Agent. HA Auto Discovery always offers the connection to the old switched-off PC, but not to the new one. Other PC sensors are mapped in HA. Even multiple restarts of HA have not helped.

A special feature: The new PC - like the old one - is in a different subnet (192.168.1.x) than HA (192.168.2.x). Do I have to manually add a rule in the Windows firewall? However, other PCs in this subnet work with HASS.Agent, and I don't remember having to configure anything extra.

Does anyone have any tips?
