I don't know if it has something with the update to do, but after upgrading to 24.7.12 my (since long time working) client OpnSense server can no longer connect to the main site.I see lots of these messages in the log

Sorry for the spamming. Turns out it had to do with my DNS name provider. Just happened to coincide with the upgrade.
