Navigation by url to my polymerCLI generated starter-kit works perfectly deployed locally by ">polymer serve", but navigation by url is broken when deployed to an https site.
Entire generated app untouched is on github at https://github.com/datafundamentals/polymer1-starter-debug README describes exact details.
Entire built and deployed starter-kit untouched is at https://cliffdweller.work/view1 but emptying cache and hard reload may be necessary to display 404 if you nav by menu first.
Really hope that I just haven't skipped some docs somewhere but if so, I'm sure I'll get the flames I deserve. I've been scratching my head on how to even look it up?
The answer to this question was posted polymer error on reloading
There are two fixes required, both the use-hash-as-path property and the use of the #/ as a prefix, so a quick glance at this answer may not be sufficient.
