Notice:
This project is using an old URL. When convenient, remove the project, then add https://universeathome.pl/universe/

I tried adding and removing the project through BAM but it still has the old url which is a http address, not https.

BAM! ID: 218157
Host: Raspberry Pi 2 running Raspbian 4.9

Same notice from boinc.
Tried to manually remove and added from boinc but after bam add the project without https.

It's a notice, not an error message. Project will continue to work without problems (especially since the scheduler URL is unchanged). See (numerous) other threads with the same issue.

With some projects huge problems arose when BAM! changed to https and we were asked to switch back by the project. This results in your host not doing any work for the project for some time. Therefor I'd like somebody from the project to give the go-ahead to switch BAM! to https.

Thanks for your advice Willy. I've passed that on to the Universe@home team via a forum post that's ongoing over there. No action for almost 3 weeks now, but hopefully they'll get in contact eventually.

Hi Willy, the U@H admin got back to us and said he's messaged you: https://universeathome.pl/universe/forum_thread.php?id=281&postid=2946

Thanks Willy!
