Some of you might get an unmeaning error message on setting up filelink that there was an error. For me i figured it out after some (acutally a lot of) googling: When using a self-signed certificate you will get this error message. You have to add the certificate to the exceptions. Go to Setttings --\> Advanced --\> Certificates --\> Manage Certificates --\> Server and add your server there. Note that your local IP [https://192.168.178.xyz](https://192.168.178.xyz) and [https://my-nextcloud.no-ip.org](https://my-nextcloud.no-ip.org) are not the same. Add the one you will use for filelink. Only the latter makes sense unless you’re only sending emails within your private network. May I suggest the authors of this marvellous plugin to add this note in the installation instructions or even improve the plugin that you can grant the exception within the setup process? ---
