That works here!  Well done and thanks again.

Hi FinalAngel, great theme!  One thing I have found is that it doesn't seem to respect the "reverse proxy prefix" when clicking the Home button.  It wants to take me to the root level of the website instead of the Ubooquity level.  I may be doing something wrong, but I haven't had this issue with other themes.

I hope this helps and thanks for the theme!

After many months, a well-deserved hat's off to cestdelafoudre!  Once I stopped overthinking everything and just did as told, it worked.  I thought I would have to clean other things out, would have conflicts, but none of that.  There is no impact to the other websites, either.  Simply introducing this file as named and with the exact text did the trick.

Many thanks again!

Wow!  You are really helpful and it is very much appreciated!  It may be a few days before I have time to play around with this again, but I didn't want to leave you hanging in the meantime.  It may not be as simple a process as my apache knowledge is extremely limited and to begin with, and I never had a ubooquity.conf file in my setup.  Briefly, I have a single conf file (/etc/apache2/sites-available/000-default-le-ssl.conf )for ubooquity and calibre reverse proxy directives on an https (letsencrypt) configured virtual host.  I notice my file doesn't have <location> tags in it, only a single <proxy> tag.  The proxy directives stand alone.

When I played around with this the first time you posted, I did pretty much what you have taken the trouble to do for me here!  I created a new ubooquity.conf file and remarked out all the newsstand directives in the 000-default conf file.  It didn't work either.  I saw in another apache file it does include all *.conf files from the directory but I wasn't able to reach it.  Maybe I need to create another virtualhost? Then I am not sure how to get the letsencrypt business going there too..

I suppose I could post the conf file if it would help to make sense of this.

Again, your assistance here is greatly appreciated, just bear with me if I can't get back real soon with any results.

Thanks for your help, foudre!  Unfortunately I've played with this for a while and still can't get it to go for me and must be something I am missing due to my ignorance.  This worked fine before the port split, now I just can't make a go of it.  Maybe your file will help others, though! 

I've done a new installation of Ubooquity 2.1.0 and still can't get a working Apache configuration for the reverse proxy.  It seems nginx users are able to get this to work.  Is there anyone using Apache able to get to both the library and admin UIs successfully?

Hi Jack, Unfortunately that looks to be essentially what I am doing in Apache above with the result of never hitting the admin page, just directed to the library.  I also tried taking out the ProxyPassReverse directives as your ngnix rule doesn't have anything like that to no avail.  I've no idea what the hold up is.

Yeah, I tried some ham-fisted rewrite rule and couldn't get it to go.  Thanks for confirming my suspicions about two ports requiring two location clauses (prefixes).

Thanks, Tom!
