Yesterday (September 14th) the certificate used for the personnel.29th.org domain has expired. As a Cybersecurity Engineer IRL I urge you to please update it ASAP.
Currently there shouldn’t be any real security issues with this, but browsers will complain about it, and some anti-virus will completely block you from accessing the page. Pic below related.
At the worst case scenario, some malicious user could forge a page that looks alike our roster page and start sending it to other members. Since currently we can’t verify the authenticity of our own page, our members could have trouble distinguishing the real page from the fake one. With this we are susceptible to phishing attacks.
Cert wasn’t expired, nor is that what the error is indicating. It would say expired, not cert date invalid. This issue was caused by the nginx proxy container crashing. It has since been resolved.
