thank you, you’re a star!
That was it. As I’ve spent quite a bit of time digging through docs howto set it up, reading about SNI … and when it didn’t work I’ve been pretty sure I’ve messed it up there, overlooked a typo 
.
As for domain - I get it, it would be nice. But this is in isolated vlan, where I don’t have access to outside world. I’ll learn a bit howto set up certificate in home lab network in due time.
Thx for pointing out the dangling file_server - it is remnant of the time where I’ve tested whether serving static sites work.
