I recently connected a couple of new hosts. One appears to be working fine however the other is not showing any statistics with the message:

"Host ID doesn't exist in BOINC combined or doesn't have any credit."

I decided to give it a few days but it's not corrected itself. The host does have credit on the project website.

Host BAM ID = 734452
Host CPID = 4d0830a511ac60c6dfa7f0205222a486

BAM does appear to be working and communicating with the host.

Project Stats:

https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10525917
https://boinc.multi-pool.info/latinsquares/show_host_detail.php?hostid=7837
https://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=3352777

Still not working.

Could you provide a link to the problematic host?

The link to the host stats is:
https://boincstats.com/en/stats/-1/host/detail/54f6ddb298359dbc788636a8d44d57f4

And the BAM host link:
https://boincstats.com/en/bam/host/734452

I've actually just changed my e-mail across all of the projects so I was hoping this would jolt it back to life, unfortunately it hasn't yet.

Thanks

Edit:
I've just found this host which I suspect is the real host and the disconnect is between the Stats and BAM.

Did you get your stuff lined up? Changing your email address will cause a new account CPID, so there could be other stats issues as well until everything gets synchronized, which should have only taken a few days.
