RW cannot start internal web server

RW Classic 9.1.1 - MacBookAir M1 - Sonoma 14.4.1
This is coming up a lot since 2 days - very annoying!

Any cure?


Ok, as ist seems no one knows or is interested in this I did check what I changed.
I put in a %base_url% in the links for warehoused pictures and this seems to break the internal server.
Actually as I build sites for clients and have to show them under another web adress first and then publishing to the “real” address the “base_url” hack would make my life much easier and save a lot of time …
Seems like RW is not compatible with that.
