Thank you for your continued support Emily.
I tried adding entries in the CSP lists but that did not make a difference.
The pages are requested from the client browser via HTTPS :
The request is received by the reverse proxy on port 443 which then sends the request to the upstream server via HTTP on port 9996 where SmarterTrack is running (It happens that both the reverse proxy and SmarterTrack are running on the same host.):
After further digging I found the issue is rooted in C:\Program Files (x86)\SmarterTools\SmarterTrack\MRS\dist\js\common.min.js\
in the lines containing
'<link type="text/css" rel="stylesheet" href="'+options.st.baseUrl+"
The above script contains the href="'+options.st.baseUrl+"
which doesn't seem to be replaced to the base site URL that I have configured to be https://mysupportsite.com
and served to the browser as such and so it fails.
I checked that <HttpAbsolutePath> in SmarterTrack\MRS\App_Data\Config\SystemSettings.xml is set to
I tried deleting the SystemSettings.xml and re-run the setup wiizard but the <HttpAbsolutePath> is being reset to <HttpAbsolutePath> after running the wizard.
So I suspect the issue is due to to this setting.
Any suggestions on how to fix this?
