Hi all, I'm using Umbraco 13.5.2 and i've noticed something weird lately. On every page that I publish this error gets shown:

One or more errors occurred. (One or more errors occurred. (Invalid URI: The hostname could not be parsed.))

Weirdly, this only happens on production and no error is actually logged. Furthermore, the page is actually being published, even though this error is shown. Does anyone know how to fix this?

Looks like a strictly client-side backoffice error. If you F12 the traffic, is there something weird in the hostnames used there?
