Still problems to attach new pcs to this project.
Please, solve it

I tried both https and http on a new windows machine, without solution..

No solution??

Still.....

Hmmm. The Server Status page shows 11 computers registered in past 24 hours at the moment and I just attached this windows laptop and received tasks.
What does the event log have to say about the attach attempt?

What does the event log have to say about the attach attempt?

16/12/2020 16:59:38 | | Fetching configuration file from https://ralph.bakerlab.org/get_project_config.php
16/12/2020 16:59:49 | | Project communication failed: attempting access to reference site
16/12/2020 16:59:51 | | Internet access OK - project servers may be temporarily down.

That's strange, i cannot understand.
I copy/paste the log message from a machine and in the message the fetching configuration is from HTTP withour S , but when i paste here in the forum (and quote) the message, is from httpS://ralph.bakerlab.org/get_project_config.php .

The machine is my wife notebook and, in the past, there is Ralph, but before introduction of HTTPS. Maybe the problem is this. Maybe i have to delete all the files and folder of the project

Can you see https://ralph.bakerlab.org/get_project_config.php if click on it?

The page should look something like this

<project_config>

If you can see that page, so should the BOINC Manager. Maybe try a full detach and re-attach to this project.

Solved!!
I clear completely the Boinc folder (C:programdata) and update the client to the latest version.
And now attach correctly!

Bravo! And documenting your struggles with this may help others with similar symptoms in the future.
