Einstein@Home: Notice from BOINC
This project is using an old URL. When convenient, remove the project, then add http://einstein.phys.uwm.edu/

Howdy,
I am a technical person, but not professional the way y'all are. I do not know how to 'remove, then add' that URL. I would appreciate help in the form of a list of steps to accomplish the intended results of your notice.
Thank you.

BOINC Version 7.16.5 (x64)wxWidgets: 3.0.1 Einstein@Home, Windows 10 PRO Processor: Intel (R) Core (TM) i7-4770 CPU @ 3.40 GHz Installed Memory: 16.0 GB, I don't know it I installed BOINC as a Service or not.
Thank you again.

How did you add (attach to, start computing for) the Einstein project in the first place? I assume you were shown a list of projects to choose from when you first ran BOINC?

On that assumption,

0) Finish any work for Einstein that may be running, and report it. The following steps are destructive.
1a) In BOINC Manager, switch to 'Advanced' view (Ctrl+Shift+A)
1b) On the 'Projects' tab, click on the Einstein project.
1c) Click on 'Remove' in the list of command buttons to the left of the pane.
2a) From the 'Tools' menu, select 'Add project...'.
2b) Select the Einstein project in the list that appears
2c) Read the Project URL in the text box below the list of projects.Confirm it is exactly the same as the url you were given in the message (it is on mine)
2d) follow the chain of 'next' buttons, filling in the boxes as a 'returning user'.

And that's it. If you attached a different way, please tell us about it.

I have the same message. Referring to Richard post, that is how I
added Rosetta the first time. I clicked add project to look at it is
the same url.

That's not the point. If you use an Account Manager or boinccmd, what you see or what you type is what you get.

But if you use BOINC Manager, there's an extra step. BOINC Manager (only) goes to look up what the right answer should be. It contacts the project, with a

http://boinc.bakerlab.org/rosetta/get_project_config.php

Note that's a simple (insecure) http: request, but it returned (a couple of minutes ago)

<project_config>
  <name>Rosetta@home</name>
  <master_url>https://boinc.bakerlab.org/rosetta/</master_url>
  <web_rpc_url_base>https://boinc.bakerlab.org/rosetta/</web_rpc_url_base>
  ...

You will be attached to the "master url", as shown in that reply - the secure one they're asking you to use from now on.

Ok, I stopped my processing, removed the file, stopped the
application, restarted my computer, restarted boinc, added
the project, after the update, received the same message.

What manager are you using?
BOINC, BAM, GPUGrid, other?

Boinc

Since I posted I installed a new hd on my pc and
reinstalled everything instead of copying things over
and I no longer have that message. Installed though
the same way I posted above.

I would like to give the hint, to check the project url while adding the project again. I just had to add the s in https by myself in one case. There is no need for a restart or reinstallation.
