I have an snap installation of Nextcloud on Debian 10 and am encountering a strange issue. I can stand up other webservers on my local network and can resolve their addresses just fine; however externally when I try to access them I’m redirected to the nextcloud ‘untrusted domain’ page, despite being on completely different subdomains and machines.
I’m not trying to access the Nextcloud instance via a trusted domain, simply other subdomains on my network. Ican access Nextcloud fine on that subdomain. The problem is that this “untrusted domain” page appears on the every single subdomain. Nextcloud just takes all traffic pointed at this box or others and returns this “untrusted domain” page.
