Since Cloudflare just had some issues we lost the Connection to our Vault.
What i would expect that when I restart RDM i can select offline and continue to work with the Cached vault.
What I got, a greyed out Offline Button and a non working Online connection.
Cache is setup to 7 days and i was connected right before... so what did I do wrong?

Ended up here with exactly the same thought. Historically, the database was local with backup to cloud. That worked fine. But now we appear to be purely online only. I was offered an offline option but RDM didn't display any entries and then hung on what looked like a logon prompt.
Vast numbers of services relying on Cloudflare is a real bad idea... it's a single point of failure. Imagine a bad actor working out how to hurt most people at once...
I've just done an export of the RDM file and added to the monthly maintenance checklist...
