Encrypted DNS stops working after Unifi Gateway Ultra reboot

Hi,

I have a question for you guys:

I have a Unifi Cloud Gateway Ultra setup with encrypted DNS.
The DNS settings on the WAN interface are set to cloudflare and the encrypted DNS is set to my own selfhosted Adguard Home (on a VPS). The issue is, whenever I have to reboot the Gateway, the internet stops working. The quick fix for this is to temporarily disable the encrypted DNS and turn it back on again. Anyone else experiencing this or know how to permanently fix this issue?

Thanks in advance.
