@pierrebrunet Thanks.

@Bryanvh Looking at the code, I saw that an exchange was taking place via this certificate. So when you told me that the master certificate was missing, I tried to put myself in the same situation as you (by removing the certificate) and trying to join the pool. Having encountered the same error as you, I determined that running these commands fixed the problem. Indeed, I think the upgrade from 8.2 to 8.3 is the cause. To be more precise, a change occurred in the XAPI during the certificate exchange in version 8.2, and I think it's possible that your 8.2 host wasn't up to date when it upgraded to 8.3 (I'm not sure). In any case, I'm glad your problem is solved.

@LucienLassalle — Thanks Lucien, appreciate the detailed reply. Glad we landed on the same result independently, and the CI/testing rationale makes complete sense — stability matters more than rushing a same-day patch. Good to see June Updates #1 out covering Fragnesia, ptrace_may_dream, and Pintheft, and good to know CIFSwitch will likely be treated the same way. I'll keep checking the blog and the VSA registry. And noted on security@ for future reports. Thanks for the great work as always.
