Hey @capetom,

I haven’t seen any reports of this coming in from anybody else.

Maybe try @Heroic_Nonsense’s suggestion in this post [Permission denied. Couldn't start the internal web server on 127.0.01:21 - #2 by Heroic\_Nonsense](https://forums.realmacsoftware.com/t/permission-denied-couldnt-start-the-internal-web-server-on-127-0-01-21/43606/2) and see if it fixes your issue.

Also make sure the “Web Server Port” field is empty on that same page. Let RapidWeaver auto-select the port for you.

Let us know how you get on.
