When using BM to add World Community Grid the prefix https is used
Unaccountably, WCG complains that it need to be "http" and I get 1000's of error messages that show up like this:

56	World Community Grid	12/17/2021 2:02:52 PM	This project seems to have changed its URL.  When convenient, remove the project, then add http://www.worldcommunitygrid.org/	

That message originates in the client and is not from the project. It is generated when the reply url is not the same as the current url.

I scanned some of the xml in ProgramData\boinc in my lenovo system and found the following

--------- SCHED_REPLY_WWW.WORLDCOMMUNITYGRID.ORG.XML
<master_url>http://www.worldcommunitygrid.org/</master_url>
      <url>https://www.worldcommunitygrid.org/research/viewAllProjects.do</url>
---------- SCHED_REQUEST_WWW.WORLDCOMMUNITYGRID.ORG.XML
   <source_project>https://www.worldcommunitygrid.org/</source_project>
C:\ProgramData\BOINC>find /i "http:" *world*.xml
---------- ACCOUNT_WWW.WORLDCOMMUNITYGRID.ORG.XML
---------- MASTER_WWW.WORLDCOMMUNITYGRID.ORG.XML
---------- SCHED_REPLY_WWW.WORLDCOMMUNITYGRID.ORG.XML
<master_url>http://www.worldcommunitygrid.org/</master_url>
---------- SCHED_REQUEST_WWW.WORLDCOMMUNITYGRID.ORG.XML
---------- STATISTICS_WWW.WORLDCOMMUNITYGRID.ORG.XML

On the systems where I did the detach and re-attach the following differences

D:\ProgramData\Boinc>find /i "http:" *world*.xml

---------- ACCOUNT_WWW.WORLDCOMMUNITYGRID.ORG.XML
    <master_url>http://www.worldcommunitygrid.org/</master_url>

---------- MASTER_WWW.WORLDCOMMUNITYGRID.ORG.XML

---------- SCHED_REPLY_WWW.WORLDCOMMUNITYGRID.ORG.XML
<master_url>http://www.worldcommunitygrid.org/</master_url>

---------- SCHED_REQUEST_WWW.WORLDCOMMUNITYGRID.ORG.XML
   <source_project>http://www.worldcommunitygrid.org/</source_project>
    <source_project>http://www.worldcommunitygrid.org/</source_project>

---------- STATISTICS_WWW.WORLDCOMMUNITYGRID.ORG.XML
    <master_url>http://www.worldcommunitygrid.org/</master_url>

So, after detaching and re-attaching all the request, reply, sched xml files are consistent as "http". I have had to do this on every system as that error message is printed up for every transaction which make the log file badly cluttered. What is strange is that the client_state.xml uses https and does not generate any problems and for that matter, not making the HTTP change has only a cosmetic effect: Lot of error message.

I assume the fix to this is to have WCG use "https" in their reply.
Alternately, it would be nice if once the user is notified there are no further error messages from the same project.
For that matter there should be no back-to-back identical error messages.

Observation: If WCG got the "request" and "replied" then why is there a problem? If they cannot reply because the url is wrong there is obviously a real problem.
