It is not 100% clear to me what you mean by speaking about the **access through untrusted domain** error. Are you sure that it is shown in the web browser because the certificate cannot be validated or because you haven’t set the **trusted\_domains** parameter of Nextcloud? If you meant the following message, you should read e.g. this posting: [Nextcloud useless due to "untrusted domain" error](https://help.nextcloud.com/t/nextcloud-useless-due-to-untrusted-domain-error/33119) ![](https://help.nextcloud.com/uploads/default/original/2X/e/e626995e76969bd14c9c1530fc696f616bc5a231.jpeg) Concerning **"Is there a method of generating the SSL cert that doesn’t rely on port 80? "** you are also speaking in miracles. Do you want to generate a Let’s Encrypt certificate or what do you mean? If you’re speaking about Let’s Encrypt, it might be of interest for you that, beside **http-01** (80/tcp) the protocol **tls-alpn-01** (443/tcp) is also supported. See [Deploying Let’s Encrypt certificates using tls-alpn-01 (https) | by Sam Decrock | Medium](https://medium.com/@decrocksam/deploying-lets-encrypt-certificates-using-tls-alpn-01-https-18b9b1e05edf) for more details. --- _[View the full topic](https://help.nextcloud.com/t/how-to-get-around-access-through-untrusted-domain-error/48179)._
