I've trying to set up an IIPImage server but the Images won't display: https://oooledge.de/wisski_views/b719fd1ac3844863103c508912965b883443

First here are logs, configs, modules and permissions:

[2019-08-16 13:22:11]: command iipsrv.fcgi not in docroot (10000)

apache2 error.log

The Console Output by accessing a side, using the IIPImage Server says:

There are several reasons I can imagine why it's not working:

1) I can reach the server over the IP-adress: , but get an internal error 500 by trying the domain path: https://oooledge.de/fcgi-bin/iipsrv.fcgi

Maybe it has to do something with the base_urls or with the IP to Domain resolving.

2) docroot and suexec
Because the suexec.log mentioned the docroot, I've tried to find out my docroot for suexec, but

suexec -V 

didn't work (suexec: command not found)

I have installed the suexec-custom package (suexec -V still do not work) and I have a /etc/apache2/suexec/www-data file with this content:


# The first two lines contain the suexec document root and the suexec userdir
# suffix. If one of them is disabled by prepending a # character, suexec will
# refuse the corresponding type of request.
# This config file is only used by the apache2-suexec-custom package. See the
# suexec man page included in the package for more details.

3) Access-Control-Allow-Origin
Since the console output of https://oooledge.de/wisski_views/b719fd1ac3844863103c508912965b883443 says something about

I've tried the timeout stuff and so on mentioned in others posts, but I don't think it's a latency problem.
Thank you for your help!


The answer lies in the use of the Plesk enviroment. Plesk 17.8.11 have own configs for suexec and it is not possible to alter the settings - so the solution is to not use Plesk, if you want own suexec configs, docroot etc.
