Ok, thats good to know because the problem popped back a week later.

Created a new NFS destination (old truenas hardware died, moved zfs pool to a PC)

Deleted old destination, new one has the same files.

Yes tried that, after 10-15 minutes back to the error list.

Ok, this time it worked?! I'm not questioning it, case closed.

I have tried https://docs.cloudron.io/email/#solr-index-corruption

no change. the mail service has 20GB and is using 3.xGB

What do ?

So I went to use it, last month, connects as usual but fails to access the LAN. Tried to look at its settings and VPN now has ip ranges not to do with my LAN.
Reading through the updates something changed in may... So How do I make my 192.168.1.0/24 LAN subnet accessible again?
The VPN wont allow me to change its openVPN range to the actual LAN range.
EDIT : NVM found the all traffic goes through tunnel tick box, work again

version Minio RELEASE.2025-10-15T17-29-55Z
io.minio.cloudronapp@5.3.0-1
automatic updates are on, the check for updates runs without finding anything new, and last updated 4 months ago.

Thanks! that link had info that solved another issue I was having.
BTW the first link is in the app, under info > show checklist> guide has bad URL.

My users have come from outlook, so they are used to in-application ability to set an out of office reply that doesn't require leaving the app running. Using sogo web interface is unfamiliar to them, and quite frankly odd.
from the inbox page you must pick preferences, mail, vacation, enable autoreply. then fill out the page. you can't leave the page until you save, or undo any changes. you can't go back to general preferences to check the timezone is correct if you ticked the enable box on mail>vacation. you cannot set a different autoreply for internal or external senders. it's very much got the appearance of an after thought.IMO, Ideally a person using an application like thunderbird could set an autoreply, much like the other features of synced calendars & contacts. but there seems to be no mechanism for that to work.

no it hasn't ? I still get the 404 error
https://cloudron.io/documentation/apps/minio/#admin-credentials then redirects to
https://docs.cloudron.io/apps/minio/#admin-credentials
and 404

Update: I restarted the updates as I had noted there were some more, and after catching up the app works fine.

what features does / will it have that sogo is missing? will the calendar have a easy to understand out of office?

Working version : Invoice Ninja 5.13.22

I tried a restart, no change, I hadn't used it since the last backup so I have restored to then, and it works again.
I have disabled automatic updates for now.

Get this error

Error :: to 'BuiltMap<String, int>' failed due to: Deserializing to 'int' failed due to: type 'List<Object?>' is not a subtype of type 'int' in type cast

I have no understanding of what that means.

Not sure exactly the cause, however the app being backed up was peertube, and a update was scheduled and failed around the same time. The fix was deleting the corrupt file in the snapshot folder on my truenas from shell. Then re-running the backup

Heres the snip of the error log...

to me it reads like its blaming the truenas destination, but the truenas reports no problems. and the file app_10da5.... is 9Gb and created on the 24th May. Should I just delete the files in the snapshot folder and let it re-create them ?

Oh, dolphin also complains about the file not existing, when I try to open or delte it, so I gues its just corrupt. /case closed.

@nebulon Yeah, I got that wrong. pretty similar names & product.
