What makes you think this is related to Alby Hub? Are all your other services’ .local interfaces working and it’s just this one that isn’t?
Assuming that you can access the interfaces of the other services, we might need to look at the Alby Hub logs.
However, if you have confused an issue with your client OS where it can’t access ANY of your .local address for individual services, then you’re probably using Windows and will need to follow this guide: Start9 | Connecting Locally
That’s a good question, I hadn’t thought of that. Because Alby Hub is the most used service, I forgot to check the others. Indeed, they are also not reachable via the .local address. Thanks for the link.
A Bonjour repair quickly solved this issue.
Thanks for your help @StuPleb
