there a misunderstanding. Desktop and mobile apps connect in different ways.
The mobile apps connect directly to pCloud via their WebDAV interface (URL). The desktop version does not connect to anything. It uses the cloud provider’s sync client. Means: you create your vault local with cryptomator, and then use pCloud Sync Client (or other compatible sync clients) to sync your encrypted vault files to pCloud.
The Port you are mentioning is for the virtual drive. If you choose to use WebDAV as virtual filesystem, you can change the port if you want/need to. Please do not missmatch with the WebDAV connection within the android app.
so you need to connect the android app via WebDAV and enter the pCloud WebDAV URL.
Please note: pCloud WebDAV connection was reported as quite not reliable.
