[Xymon] XymonPSClient CPU graphs missing over HTTPS

[Kris Springer]

So I did a test on a Windows 11 host machine that's local to the Xymon 
Server instead of outside the network.  The host has been using the 
regular HTTP method (port 1984) successfully for a long time without any 
problems.

Here's the redacted xymonclient_config.xml it uses that works fine.

<XymonSettings>
   <servers>REDACTED.REDACTED.com</servers>
   <clientlogfile>c:\program files\xymon\xymonclient.log</clientlogfile>
   <clientconfigfile>c:\program 
files\xymon\clientconfig.cfg</clientconfigfile>
   <clientfqdn>0</clientfqdn>
   <clientlower>0</clientlower>
   <wanteddisks>2 3 4</wanteddisks>
   <clientremotecfgexec>1</clientremotecfgexec>
</XymonSettings>


I then edited the xymonclient_config.xml to use HTTPS and restarted the 
XymonPSClient service.  The 'CPU' graphs stopped populating and the 
'Files' tests that previously worked fine all now say 'Could not 
determine size of directory'.
Here's the HTTPS (port 443) config.

<XymonSettings>
<serverUrl>https://REDACTED.REDACTED.com/xymon-cgi/xymoncgimsg.cgi</serverUrl>
   <serverHttpUsername>REDACTED</serverHttpUsername>
   <serverHttpPassword>REDACTED</serverHttpPassword>
   <clientlogfile>c:\program files\xymon\xymonclient.log</clientlogfile>
   <clientconfigfile>c:\program 
files\xymon\clientconfig.cfg</clientconfigfile>
   <clientfqdn>0</clientfqdn>
   <clientlower>0</clientlower>
   <wanteddisks>2 3 4</wanteddisks>
   <clientremotecfgexec>1</clientremotecfgexec>
</XymonSettings>


I feel like anyone can easily reproduce this issue. I would appreciate 
it if anyone could give me a clue as to how to resolve this.
I've also been working with ChatGPT to resolve this issue, but none of 
the suggestions it's offered have resolved the issue, and it's advising 
the Xymon community will be able to help better.
