Launch of jupyterlab (rstudio server as well) gets Not Found

I just now caught what you said about regex vs host_regex. I’ve fixed that, but it still did not work after regenerating, restarting httpd, and restarting the webserver.
Looking for other differences in the configuration, I found that the ood.ccre.langston.edu-le-ssl.conf file was both named wrong (had the shorter version of the name vs the FQDN) and that it was malformed on the inside. Once that was fixed and everything was restarted, JupyterLab fired up. RStudio-Server fired up as well. On to the rest of configuration. Thank you for your patience.
