Invalid Let's Encrypt certificate?

I just opened up the NextCloud iPhone app and it said the SSL cert for is invalid.

It asked me if I want to accept anyway, and I said “Yes”. Now it’s not coming up anymore, but I’m not sure if the issue is resolved or not.

There was a huge Let’s Encrypt expiration wave across the internet this month - is this related?

What’s the best way to confirm that the issue is resolved? Thanks!

Hi @bubbleboy , thanks for noticing.
There is a bug in the IPhone app that reports it as invalid for some reason, a lot of people are having the same problem: Nextcloud iOS App - Invalid Certificate · Issue #1682 · nextcloud/ios · GitHub
But our certificate is valid, so there’s nothing to worry about, you can just ignore the message.
