2024-03-28T12:55:24.28+00:00 This is a newly created SQL Managed Instance with a large restored database with a single publication with around 550 articles. 4 subscriber databases (SQL 2022 Web Version recently deployed) - SNapshot agent created snapshot to Azure storage - this took around 6 hours. On completion 4 subscributuin distribution agents started 3 of these have successfully played the snapshots and are now in syn. 4 one has this error. I drop the subscription and recreated - still the same error.
So yes distribution DB is accessibledistribution history:
Starting agent.Distribution agent for subscription added.

Are they all fully patched to the latest CU?
